Question

Christine went shopping and bought each of her six nephews a gift, either a video costing $14.95 for a CD costing $16.88. She spent $99.35 on the gifts. How many videos and how many CDs did she buy?

Answer 1

Let v = number of video's she bought

Let c = number of CD's she bought

v+c=16

1495v+1688c=9355

Multiply both sides of (1) by 1495

and subtract (1) from (2)

-1495v-1495c=-8970

193c=386

c=2h
