Question

1. a cell phone company charges $20 for the month and $2 per international phone call. last month johnnys bill was $60. how many international calls did he make? type a response

Explanation:

Step1: Define variables and equation

Let \( x \) be the number of international calls. The total cost is the monthly charge plus the cost per call times the number of calls. So the equation is \( 20 + 2x = 60 \).

Step2: Subtract 20 from both sides

Subtract 20 from each side to isolate the term with \( x \): \( 2x = 60 - 20 \), which simplifies to \( 2x = 40 \).

Step3: Solve for x

Divide both sides by 2: \( x=\frac{40}{2}=20 \).

Answer:

20
