Answer:
I think it is 350(1.2)^t because you take the starting amount (350) and then multiple it by the growth rate (which is 20%, but when added to 100 and the put into a decimal is 1.2) raised by the number of hours (t).
I hope this helps.
Step-by-step explanation:
A. She can multiply the bottom equation by -4 and then add the equations to solve for h.
-4g - 15h = -17
4g - 20h = -52
Add them to get
-15h = -17
-20h = -52
From here, you can solve for h.
24-20 311-310 107-110
x=-14
-x-11^2+1
-x-11^3
-x^14
