Question

Kayla purchased 4 paperbacks and 3 hardcovers books at the library sale. The paperbacks were 15 cents each, and the hardcovers were 75 cents each. If Kayla paid with a $5 bill, how much change was she owed?

Answer 1

Kayla was owed $2.15 in change.

Step-by-step explanation:

To find out how much change Kayla was owed, we need to calculate the total cost of the books and subtract it from the amount she paid with her $5 bill.

Number of paperbacks: 4, Cost per paperback: 15 cents

Total cost of paperbacks = 4*15 = 60 cents

Number of hardcovers: 3, Cost per hardcover: 75 cents

Total cost of hardcovers = 3*75 = 225 cents

Total cost of books = Total cost of paperbacks + Total cost of hardcovers = 60 cents + 225 cents = 285 cents

To convert cents to dollars, we divide by 100. Total cost of books in dollars = 285 cents / 100 = $2.85

Change owed to Kayla = Amount paid - Total cost of books = $5 - $2.85 = $2.15

Therefore, Kayla was owed $2.15 in change.
