If a represent the number of apples purchase at 15 centa each and b represents the number of banana purchase at 10 cents each, which of the following representa the total value of the purchase

Total value of the purchase = 0.15A + 0.10B

unit cost of apple = 0.15
unit cost to banana = 0.10

Total value of apple = 0.15 * A(number of apples)
Total value of banana = 0.10 * B(number of bananas)

Total value of the purchase = 0.15A + 0.10B

For example: Apple = 5 pcs; Banana = 10 pcs

Total value of the purchase  = 0.15(5) + 0.10(10)
Total value of the purchase = 0.75 + 1.00
Total value of the purchase = 1.75

Total value of apples = 0.75
Total value of bananas = 1.00
