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.

(20-0.6P)

Step-by-step explanation:

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

Since 1 dollar = 100 cents

Then,  60 cents =

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)

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
