Question

The Middle School Student Council is organizing a
dance and has $500 to pay for a DJ. DJ Dave will charge
$200 to set-up and spin for the first hour. For 4 hours, the
total is $425. Write an equation that represents the
relationship.

Answer 1

Okay so we know theres a 200 dollar startup fee for the first hour. Then for 4 total hours, the final price is 425. We can express that by

425=3x+200

As the first hour is 200 dollars already, and so the next 3 are regular price.
