Question

A cell phone company charges a monthly fee of $18 plus $2 for each call. A customer's total cell phone bill this month is $50.50. Which equation can be used to determine how many calls were made?
1) 2x + 18 = 50.50
2) 2x + 50.50 = 18
3) 18x + 2 = 50.50
4) 50.50x + 2 = 18

Answer 1

Answer:

1) 2x + 18 = 50.50

Step-by-step explanation:

Let's break it down:

- The variable "x" represents the number of calls made.

- The term "2x" represents the cost of the calls made

- The constant term "18" represents the fixed monthly fee.

- The equation states that the total cell phone bill, including the fixed fee and the call cost, equals $50.50.

So, the answer is 1) 2x + 18 = 50.50
