Question

Renting a roller rink for your birthday costs $250 plus $10 per person. The total charge

for your party was $400. Translate this information into an equation using a to
represent the number of guests at your party.
Using your equation, determine how many people attended your party.

Answer 1

the equation would be 250+10x=400
250 for renting the space and 10 per person and x represents the amount of people and 400 was the total with the rent and the cost for the total amount of people

step by step of solving that would be
250+10x=400
-250 -250
10x=150
10/10 150/10
x=15

so there were 15 people at the party

Answer 2

15 people attended the party
