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.
Answer:
$5,500
Step-by-step explanation:
Let A be the amount invested at 3%, B the amount at 4%.
Total value:
1.A%2BB=8000
Interest:
Multiply eq. 1 by -3 and add to eq. 2,
-3A-3B%2B3A%2B4B=-24000%2B29500
highlight%28B=5500%29
Then from eq. 1,
A%2B5500=8000
highlight%28A=2500%29
