Answer:
18r + 11t
(Because there are 2 different variable, don't combine them together)
B. Since she earned 35 (+35), spent 15 (-15), bought a book for $7 (-7) and got 10 dollars from mom (+10)
For continuously compounded interest:
Amount = Principle * e^(rate * time)
A rate of 8% converted to a decimal value: r=0.08
With time t=4
and amount 1190
Plug all these values in,
1190 = Principle * e^(0.08 * 4)
And use your calculator to solve for the principle.
Maybe we'll call it P to make things easier.
1190 = P * e^(0.08 * 4)
1190 = P * 1.377
The principle is being multiplied by this 1.377,
divide by 1.377 to undo the multiplication.
864.11735 = P
