Question

I need to figure out estimation with decimals

Answer 1

10 CDs

Explanation:

First, let's round the cost of each CD to the nearest whole number.

• 6.98 ≈ 7.00

The closest multiple of 7 to 75 is 77.

• Then, it would make sense that Sean can buy 11 CDs. However, he has a little bit under 77 dollars, so he can only buy 10 CDs.

(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)
