Ruth wants to buy a skateboard for $56. She has $90 in her account. She spent $11.65 to buy stationary. She also wants to buy some comic books for $3.72 each. What is the maximum number of comic books, n, that Ruth can buy so that she has enough money left to buy the skateboard?
n >6
n < 6
n < 16
n > 16
To find out the maximum number of comic books Ruth can buy, we need to subtract the cost of the skateboard, the stationary, and the cost of the comic books from her account balance.
First, subtract the cost of the skateboard from her account balance:
$90 - $56 = $34
Then, subtract the cost of the stationary from the remaining balance:
$34 - $11.65 = $22.35
To find the maximum number of comic books she can buy, divide the remaining balance by the cost of each comic book:
$22.35 / $3.72 ≈ 6
Therefore, the maximum number of comic books Ruth can buy is 6, so n < 6.
