What if she only had $2.00 to spend?

Solutions

Expert Solution

Janice will purchase potatoes as long as the worth of potatoes to Janice is atleast equal to the price of potatoes

Price of potatoes = 1

When income is 5, she will purchase 3 kg of potatoes as the worth of 3rd kg = 1.05 > 1 but the worth of 4th kg < 1

When income is 2, she will purchase 2 kg of potatoes as the worth of 3rd kg = 1.14 > 1 and she does not have income left to buy the 3rd kg although she would like to.
