I need to figure out estimation with decimals

Answer:
10 CDs
Step-by-step explanation:
First, let's round the cost of each CD to the nearest whole number.
The closest multiple of 7 to 75 is 77.
(If we were to do the actual calculations, 75/6.98 is 10.744.. and so on, so we can confirm he can buy no more than 10 CDs)
