Answer:
- V(t) = 25(1.07^t)
- V(t) = 40(1.05^t)
Step-by-step explanation:
Put the given numbers into the given formula. It can be simplified a little bit.
Formula:
V(t) = P(1 + r)^t
<u>Coin A</u>
P = 25, r = .07
V(t) = 25(1.07^t)
<u>Coin B</u>
P = 40, r = 0.05
V(t) = 40(1.05^t)
Answer:
it is C
Step-by-step explanation:
Solve using system of equations!
Let y=total amount of money and x=hours of overtime.
mall: y=400+15x
movies: y=360+20x
Solve! Set the equations equal to each other to find x.
400+15x=360+20x
40=5x
x=8
After 8 hours of overtime the movies would pay her more.
