Answer 1

1. A catering company charges a fixed fee of $200 plus $15 per person for a party. Write an equation that represents the total cost, C, for a party with x number of people attending.

C = 200 + 15x

2. A car rental company charges a fixed fee of $50 plus $0.25 per mile driven. Write an equation that represents the total cost, C, for renting a car and driving d miles.

C = 50 + 0.25d

3. A cell phone plan charges a fixed monthly fee of $30 plus $0.10 per minute for calls. Write an equation that represents the total monthly cost, C, for making m minutes of calls.

C = 30 + 0.10m

4. A taxi service charges a fixed fee of $5 plus $2 per mile driven. Write an equation that represents the total cost, C, for taking a taxi for a distance of d miles.

C = 5 + 2d

5. A gym membership costs $50 per month plus a one-time enrollment fee of $100. Write an equation that represents the total cost, C, for having a gym membership for m months.

C = 100 + 50m
