Joshua buys p pounds of bananas for 40 cents per pound. He pays the clerk with a fifty-dollar bill. The clerk subtracts the total cost of the bananas from the fifty-dollar bill to determine the amount of change to give Joshua. Write an expression to represent this scenario. Then, determine how much change Joshua will receive if he buys three pounds of banana

Change he would get = 50-  40p

Joshua will receive $48.8 if he buys three pounds of banana.

Step-by-step explanation:

Given: Cost per pound of banana = 40 cents= 0.40 dollars  [1 cent = 0.01 dollar ]

Number of pounds bought = p

Now, total price need to pay = (Cost per pound of banana) x (Number of pounds bought ) = 0.40p

Now, He pays the clerk with a fifty-dollar bill.

So, the change he would get = 50-  0.40p  , which is the required expression.

When p= 3

then, change he would get = 50-0.4(3)=50-1.2 = $48.8

Joshua will receive $48.8 if he buys three pounds of banana.
