Willow Brook National Bank operates a drive-up teller window that allows customers to complete bank transactions without getting out of their cars. On weekday mornings, arrivals to the drive-up teller window occur at random, with an arrival rate of 30 customers per hour or 0.5 customers per minute.

(a)

What is the mean or expected number of customers that will arrive in a four-minute period?

(b)

Assume that the Poisson probability distribution can be used to describe the arrival process. Use the arrival rate in part (a) and compute the probabilities that exactly 0, 1, 2, and 3 customers will arrive during a four-minute period. (Round your answers to four decimal places.)

(c)

Delays are expected if more than three customers arrive during any four-minute period. What is the probability that delays will occur? (Round your answer to four decimal places.)

Chipolo sells a coin-sized tracking tag that attaches to keys, wallets, and other personal items. Chipolo began January with an inventory of 200 tags purchased from its supplier in November last year at a cost of $12 per tag, plus 100 tags purchased in December last year at a cost of $15 per tag. Chipolo sells the tags at a price of $30 per tag, on account with terms n/30, FOB destination. Chipolo uses a perpetual inventory system to account for the following transactions.

Assume Chipolo uses weighted average cost in its perpetual inventory system. Prepare the journal entry for each transaction

1 - Record the tags delivered to customers.

2 - Record the sale of tags to customers.

3 - Record the cost of tags sold to customers.

4 - Record the order for tags made by Chipolo from its supplier

5 - Record the cash collected from customers.

6 - Record the purchase of tags after deducting the allowance given by supplier for delay between order and shipment.

7-Record the sale of tags to customers.

8-Record the cost of tags sold to customers.

9-Record the loss of inventory at its cost.

3. A bank wants to get new customers for their credit card. They try two different approaches in their marketing campaign. The first promises a "cash back" reward, and the second promises low interest rates. A sample of 500 people is mailed the first brochure; of these, 125 get the credit card. A separate sample of 500 people is mailed the second brochure; 150 get the credit card. Are the two campaigns equally attractive to customers? Compute a 95% confidence interval for the difference in the two proportions. Answer the question of interest by interpreting your result.

Problem 7-19 Credit policy decision with changing variables [LO7-4] Fast Turnstiles Co. is evaluating the extension of credit to a new group of customers. Although these customers will provide $306,000 in additional credit sales, 11 percent are likely to be uncollectible. The company will also incur $16,900 in additional collection expense. Production and marketing costs represent 71 percent of sales. The firm is in a 30 percent tax bracket and has a receivables turnover of three times. No other asset buildup will be required to service the new customers. The firm has a 12 percent desired return. a-1. Calculate the incremental income after taxes. a-2. Calculate the return on incremental investment. (Input your answer as a percent rounded to 2 decimal places.) a-3. Should Fast Turnstiles Co. extend credit to these customers? Yes No b-1. Calculate the incremental income after taxes if 14 percent of the new sales prove to be uncollectible. b-2. Calculate the return on incremental investment if 14 percent of the new sales prove to be uncollectible. (Input your answer as a percent rounded to 2 decimal places.) b-3. Should credit be extended if 14 percent of the new sales prove uncollectible? Yes No c-1. Calculate the return on incremental investment if the receivables turnover drops to 1.6, and 11 percent of the accounts are uncollectible. (Input your answer as a percent rounded to 2 decimal places.) c-2. Should credit be extended if the receivables turnover drops to 1.6, and 11 percent of the accounts are uncollectible? No Yes

Dwyran Ltd. manufactures 3 components Alpha, Bravo and Charlie, on its new machine which has 60,000 hours available, with the 3 components being used to produce Delta which is a relatively new product and Dwyran Ltd. are trying to grow their market share. Dwyran Ltd. has orders for 5,000 units of each, from relatively established customers and Ruth is determined not to let these customers down. Other producers of the components have been sourced and Dwyran Ltd. are satisfied with the quality of these replacements and confident that they can buy them in if necessary.

The following information has been produced:

Each unit takes the following machine hours to make one unit of each component:
Alpha: 3 hours Bravo: 5 hours Charlie: 6 hours

The variable cost per unit of component is:
Alpha: £40 Bravo: £60 Charlie: £50

The buy in purchase cost of each component is:
Alpha: £44 Bravo: £66 Charlie: £65

In order to maximise their profits how many units of each component should the company produce or buy in?
