What's the solution to Rachel bought one double pack of CD's for $20. this is $4 less than 3/4 the cost of a triple pack of CD's. What is the price of a triple pack of CD's?

I believe the answer is $32.

if 20 is 4 less than 3/4 the price then 3/4 = 20+4

3/4=24

then divide by 3 to get the exact value of 1/4 which will be 8 and then multiply by 4 to get the full value of the triple pack which is 32
