How can I solve this: Sandy decided to give one-fourth of her CDs to Jenn. Then she gives one-half of the remaining CDs to Bob. If she is left with 6 CDs,how many CDs did she have to begin with?

let the number she had be x

x - (1/4)x - (1/2)(3/4)x = 6

x - x/4 - 3x/8 = 6

times 8

8x - 2x - 3x = 48

3x = 48

x = 16

She had 16 CDs

check:

she had 16, gave 1/4 away

leaving her with 12

she gave 1/2 of those away, so she gave 6 of the remaining 12 away, leaving her with 6

-all checks out!
