144 classes. each class is 10 minutes. 6X24= 144
If the TV is 70% off, then that means she paid 30% of the original cost. If 30% of the original cost is $120, then...
30% * x = 120
.30x = 120
x = 120/.30
x = 400
The original cost was $400
It would be (rounded) 5
Because
31 / 6.15 = 5.04065
Hope this helped
Have a great day/night
The digits are 5 and 6...
