The ratio of football cards to baseball cards is 3:2 and the ratio of baseball cards to basketball cards is 3:1. To solve this problem, we need the baseball card side of each ratio to be equal so we need to rewrite the ratios in terms of a common number of baseball cards. (Think of this like finding the common denominator when adding fractions.) The ratio of football to baseball cards can also be written as 9:6 and the ratio of baseball cards to basketball cards as 6:2. So, the ratio of football cards to basketball cards is football:baseball, baseball:basketball or 9:6, 6:2 which reduces to 9:2.

By buying two shirts, Frank will save $48 x \( \frac{35}{100} \) = \( \frac{$48 x 35}{100} \) = \( \frac{$1680}{100} \) = $16.80 on the second shirt.

A factor is a positive integer that divides evenly into a given number. For example, the factors of 8 are 1, 2, 4, and 8.

Calculate the number of vans needed by dividing the number of people that need transported by the capacity of one van:

vans = \( \frac{92}{15} \) = 6\(\frac{2}{15}\)

So, it will take 6 full vans and one partially full van to transport the entire team making a total of 7 vans.
