Need more information
Step-by-step explanation:
I need to know what percentage/fraction of the book she read in 1 hour or any other information about the rate she is reading
You need to find 30% of 90
You can do this by finding 10%
10% of 90 = 0.1 x 90 = 9
Then you can times this value by 3 to find 30%
9 x 3 = 27
27 cars are two-toned
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
