...take to load 6 1/2 trucks? A warehouse received 250 orders in April, and 300 orders in May. What was the percentage of increase in orders from April to May?

A banner requires 1 1/3 sections of of plastic. How many banners can be made from 12 sections of plastic?
 
42 / 3.5 = x / 6.5
3.5x = 273
x = 78 min

250 + 250x = 300
250x = 50
x = .2
20% increase

12 / (4/3)
12 * (3/4) = 9 banners
