Ahmed wants to earn some extra pocket money while on his summer break, which is 5 weeks long. He plans to work for three days a week and enjoy his vacation the rest of the week. He has identified that car cleaning is a good business in his locality. He buys a trolley for $500 to carry water, detergent, brushes, towels, and other items, and he spends about $2 per car on these items.
a. If Ahmed charges $10 to clean one car, how many cars would he need to clean to breakeven?
b. If Ahmed cleans about 10 cars per day, how much money does he expect to make?
c. Another possibility for Ahmed is to clean the open parking
lots (areas, not cars). To do this, he need to hire a truck for
$1,500 and hire a driver on an hourly basis, which, including gas,
would cost him about $25 per parking lot. Ahmed estimates that the
truck helps him complete four parking lots per day. If he charges
$125 per parking lot, would this be a better alternative than
cleaning cars?
Summer break duration = 5 weeks
Ahmed plans to work for 3 days a week
Total days he would work in the 5 week duration = 5*3 = 15 days = D
Fixed cost of buying a trolley, F = $500
Variable cost of other consumables, c = $2/car
Ahmed charges to clean a car, p = $10
a. Breakeven = F/ (p-c) = 500 /(10-2) = 62.5
On average he needs to clean 62.5 cars to breakeven.
b. If Ahmed cleans 10 cars a day, he can clean D*10 = 15*10 = 150 cars in the 5 week duration
His revenue from 150 cars = 150* 10 = $1500
His cost = 150*2+500 = 300+500 = $800
He can make 1500-800 = $700 if he cleans 10 cars per day
c. Fixed cost for hiring a truck = $1500
The variable cost for hiring driver and other consumables = $25/parking lot
He charges for cleaning = $125/parking lot
Ahmed completes cleaning of 4 parking lots a day
He can clean D*4 = 15*4 = 60 parking lots in the 5-week duration
The revenue from 60 parking lots = 60*125 = $7500
The cost involved = variable cost + fixed cost = 60*25+1500 = $3000
He can make 7500-3000 = $4500 in the 5 week duration.
So, yes, this is a better alternative than cleaning cars.
