Ella and Mia went on a camping trip. The total cost for the trip is $124 which the girls divided evenly. Ella paid for 4 nights at the campsite and $30 for the supplies. Mia paid for 2 nights at the campsite and $46 for supplies. Write an expression to find out the cost of one nights stay. Explain what each variable in your expression means.

4c + 30 + 2c + 46 = 124

Step-by-step explanation:

The trip cost $124.

Let c = cost per night at the campsite.

Ella paid: 4c + 30

Mia paid: 2c + 46

Total: 4c + 30 + 2c + 46

The total amount was $124, so we get the equation:

4c + 30 + 2c + 46 = 124

answer: the common difference is -0.10
