Question

A music store sold 300cds and 100cd players. If each cd cost $12 and each cd player cost $35, what was the store total earnings

Answer 1

So with what we know we can set up two equations to  solve for the CDs and the players.

$12(300) = total earnings for cds

= $3600 total cds sold

$35(100) = total earnings for cd players

=$35000

add both of the totals of the CDs and the CD players to get the total earnings

$3600+$3500 = $7100 gained in total from both products sold
