Question

Satchi found a used bookstore that sells pre-owned DVDs and CDs. DVDs cost $9 each, and CDs cost $7 each. Satchi can spend no more than $45.

Answer 1

If you are looking for how many DVDs and CDs Satchi can buy then Satchi would be able to buy 2 DVDs and 3 CDs for a cheap price or 3 DVDs and 2 CDs for a more expensive price.

Budget: $45

DVDs: CDs:
$9 $7

Add $9 + $7 = $16
Add again, which would equal $32
You can either buy 2 DVDs and 3 CDs which is $32 + $7 = $39 or 3 DVDs and 2 CDs which is $32 + $9 = $41
