Question

The classrooms in Okahurst School District are painted every summer. Seven gallons of paint are needed to paint 3 classrooms. How many more gallons are needed to paint the 129 classrooms at North High School than the 48 classrooms at Edgewater Elementary? Assume the situation is proportional

Answer 1

189 Gallons

Explanation:

7 gallons for 3 classrooms, so 7/3 for 1 classroom

multiply 7/3 * 129 to get 301 gallons at North High School

multiply 7/3 * 48 to get 112 gallons at Edgewater Elementary

301 - 112 = 189 gallons more at North High School than at Edgewater Elementary
