A company sells $15 album for every 100 people who see their ads online. What’s their revenue if 20000 people see their ad?

Answer 1

Hey!

The rate is 15$ for every 100 people. We want to know $ x for every 20,000 people. Setting up a proportion, we have:

15 = x

100. 20,000

Cross multiply, then divide to get x dollars! Let me know if you have questions.

Answer 2

This is a simple proportion.

Let R represent the revenue received if 20,000 people see the online ad.

$/people = 15/100 = R/20,000

Solving R = $3000

Answer 3

100/15 = 20,000/R

1/15 = 200/R

R = 15(200) = $3,000
