Answer:
161 minutes
Step-by-step explanation:
Bill pays a monthly fee for his long distance phone service = $7.00
and call charges per minute = 7 cents
1 dollar = 100 cents
Therefore 7 cents = [tex]\frac{7}{100}[/tex] = $0.07
Last month, Bill's long distance bill was $18.27.
Let Bill used the phone service for x minutes
The equation for his uses in minutes :
7.00 +(0.07x) = 18.27
0.07x = 18.27 - 7.00
0.07x = 11.27
x = [tex]\frac{11.27}{0.07}[/tex]
x = 161 minutes
Bill was billed for 161 minutes.
