Answer: 160 minutes
Explanation:
Make an equation
She is only charged 0.17 per minute, but we don’t know how many minutes. We do know her total cost was $26.68
0.17m=26.68
Divide by 0.17 on both sides
m=159.941176
Rounded to the nearest whole number,
m=160
So, she used about 160 minutes
Hope this helps!
