The highschool student council has decided to have a dance-a-thon and needs to hire a disk jockey for the event. Council members have investigated 3 companies. Gabe's Mobile Music charges $60 per hour. Derek's DJ Service charges $100 plus $40 per hour. Solid Sounds charges $175 plus $30 per hour. Which company should they choose? Why?

Answer:

Solid Sounds

Explanation:

As a test, let's say the dance-a-thon lasted 10 hours. Plug in 10 hours to each:

Gabe's: $60/hr x 10 hr = $600

Derek's: $100 + ($40/hr x 10 hr) = $500

Solid Sounds: $175 + ($30/hr x 10 hr) = $475

This shows that Solid Sounds is the cheapest (no matter how many hours the dance lasts)
