Question

Elijah buys ​P​ pounds of bananas for ​60 cents per pound​. He ​pays ​the clerk with a twenty-dollar bill​. The clerk subtracts the total cost of the bananas from the twenty dollar bill to determine the amount of change to give Elijah.

Answer 1

Answer: (20-0.6P)

Explanation:

Given: Elijah buys ​P​ pounds of bananas for ​60 cents per pound​.

Since 1 dollar = 100 cents

Then, 60 cents =
`\$(60)/(100)=\$0.6`

Cost of P pounds of bananas = Cost per pound x P

= $0.6 P

He ​pays ​the clerk with a twenty-dollar bill​.

Change he will get = $ 20 - Cost of P pounds of bananas

= $ (20-0.6P)

Hence, the expression of the change Elijah will get = (20-0.6P)
