Question

A wireless phone company charges $34.99 a month for phone service. They also charge $0.48 per minute for long distance calls. If Bertha’s bill at the end of the billing period is $64.75, how many minutes of long distance calls did she make?

Answer 1

The equation would be 64.75=34.99+0.48x
64.75=34.99+0.48x now with this equation just subtract 34.99 from both sides
After subtracting you will get 29.76=0.48x
29.76=0.48x now with this equation divide 0.48 on each side to find x
Now since you dive 29.76 by 0.48 you would get the answer 62 minutes

64.75=34.99+0.48x
-34.99 -34.99
29.76=0.48x
/0.48 /0.48
63=x
