Question

Felicia had $80 when she went to a music store that charges $18 for each CD. She needs to have no less than $20 in her wallet when she leaves the store so she has enough money to buy gas for the ride home.

Which shows a possible number of CDs she could buy? Select three options.
1
2
3
4
5

Answer 1

She can spend at most 80 − 20 = $60 on CDs. Each CD is $18, so the largest whole number n with 18n ≤ 60 is 3 (18×3 = 54; 18×4 = 72 > 60).

Thus the possible choices are 1, 2, and 3.
