Answer:
123,000,000
Step-by-step explanation:
When rounding, the number that we look at is the number to the right of what we are rounding to. When rounding to the nearest million we look at the number to the right which is in the hundred thousandth position. In this case that is a 0. In rounding, if the number we are looking at is 0-4 we round down an if the number we are looking at is 5-9 we round up. Since the number is 0 we will round down. The nearest million below 123, 045, 067 is 123,000,000.
I hope this helps and please don't hesitate to ask if there is anything still unclear!
If t is the amount of time she used it, then it lost t*(5/min) percentage points; then she charged it for 2t, so it gained (2t)*(2/min) =t*(4/min) percentage points.
This means that above this time period, the phone lost t*(5/min)-t*(4/min) =t*(1/min) percentage points; because this loss is recognized to be 10 percentage points, this means t*(1/min) =10, so t=10 min.
This means that she used her phone for 10 minutes and charged it for 20 minutes.
