Answer:
$4.75
Explanation:
Tere: 215.50 in her purse. Book cost 220.25 and 95.50.
Nona: ??? Lets say x.
So, since Tere has not enough money, we subtract tere's value from the price of the book
220.25-215.50 = 4.75
Use a calculator.
So, Nona gave Tere $4.75. Which is 4 dollars and 75 cents. Which can get rounded to 5 dollars.
