<h3>
Answer: 5</h3>
Work Shown:
g = number of hours that Gary exercises
3g-2 = number of hours that Jessica exercises
(g) + (3g-2) = 18
4g-2 = 18
4g = 18+2
4g = 20
g = 20/4
g = 5
Gary exercises 5 hours per week.

Step-by-step explanation:
Future amount after 6 years will be: $10720.76
Step-by-step explanation:
Principal = $8000
Interest= 5% compounded annually
Time = 6 years
We need to find A (future amount)
The formula used is:

A= Future amount
P= Principal amount
r= interest rate
n= no of times interest is applied
t= time
Putting values and finding A
P=8000. r=0.05, n=1, t=6

So, Future amount after 6 years will be: $10720.76
