Question

Can someone help me with this math problem

Answer 1

Answer:

n=650. The customer made 650 calls within the month.

Step-by-step explanation:

To solve this problem we can set it up as the equation 0.05n+18=50.5.

The reasoning of doing is because adding the monthly fee and then the amount of calls (n) times 0.05 will give us the value of n in the equation .

First we want to get rid of 18 so subtract 18 from both sides to then get 0.05n=32.5. Next we want to isolate n by dividing 0.05 on both sides of the equation which will then give us the new equation n=650.
