Question

Joel has twice as many CDs as Mariella has. Subtracting 7 from the number of CDs Joel has and dividing by 3 equals the number of CDs Blake has. If Blake has 25 CDs, how many CDs does Mariella have?

Answer 1

Blake has 25 CD's. I know that 75 divided by 3 is 25 but you had to subtract 7 from the number of CD's Joel had before you divided by 3, so you would have to add 7 to the 75 to get the number of CD's Joel has .Then you would multiply 82 and 2 to get Mariella's total CD's which is 164.

Answer 2

41...
guess, Joel has x CDs.
so,

`(x-7)/(3) =25`
or,x =82
again,mariella have
`(82)/(2)`
=41
