Sheila Total:: 6x
<span>Sherri Total:: 5(x+10) = 5x+50
</span><span>(a) Write an equation. Let x represent the amount of one of Sheila’s deposits.
6x = 5x+50
</span><span>(b) Solve the equation. Show your work.
x = 50
</span><span>(c) Check your solution. Show your work.
6*50 = 5(50+10)
300 = 5*60
300 = 300</span>
<span>(d) State the solution in complete sentences.
I'll leave that to you.

Answer:
This does represent an exponential function , because his savings increase by a constant rate
Step-by-step explanation:
Let
x -----> the number of weeks
y ----> the amount saved
In this problem we have a exponential function of the form

where
a is the initial value
b is the base
r is the rate of change
where

---- because he doubles the amount each week
----> 
substitute

therefore
This does represent an exponential function , because his savings increase by a constant rate
4 + 4 + 5 + 5 = 18
The answer is 18m.
Hope this helps!
