Question

6. The cost to rent a room for a party is a one-time fee

of $90 plus $60 per hour for a DJ. If the cost of the party
was $300, how many hours did they have the DJ?

Answer 1

x = # of hours the DJ was booked

$90 + $60x = $300

Subtract $90 from both sides.

$60x = $210

Divide both sides by $60

x = 3.5 hours

They had the DJ for 3.5 hours
