Answer:

90 people

Explanation:

Total: $775

DJ: $250

Cake: $75

Unknown party guests each getting $5

Let the unknown be x

We can form an equation; DJ + Cake + x number of party guests = $775

250 + 75 + 5x = 775

325 + 5x = 775

Subtract 325 from both sides of the equals sign.

5x = 450

Make x the subject and divide both sides by 5

x = 90

There were 90 party guests.
