Answer 1

Answer : When income is $5 :

For 1st kilogram the price is $1.50

For 2nd kilogram the price is $1.14

For 3rd kilogram the price is $1.05

For 4th kilogram the price is $0.30 [As after 3 kilogram the price is $0.30 for remaining all kilograms]

For 5th kilogram the price is $0.30

For 6th kilogram the price is $0.30

Total price of 6 kilograms potatoes = $4.59

As Janice income is $5 hence Janice will purchase 6 kilograms of potatoes.

When income is $3 :

For 1st kilogram the price is $1.50

For 2nd kilogram the price is $1.14

Total price of 2 kilogram potatoes = $2.64

As Janice income is $3 hence Janice will purchase only 2 kilograms of potatoes. Because if Janice purchase 3 kilograms then the total price of 3 kilograms exceeds her total spendable income of $3. So, Janice buy 2 kilograms of potatoes when her income is $3.
