If one gallon equals to 16 cups, then 16 * 10 will be your answer.
10 * 16 = 160
s = # of songs
y = total amount of money
$11 + $1(35) = y
Simplify the right side
$11 + $35 = y
Combine like terms
$46 = y
If he downloaded 35 songs, he would have ti pay $46
If he downloaded s amount of songs, he would have to pay $11 + $1s = y
They would need to buy 5 dozens because the area is 56 and 12 times 5 is 60.
