Answer:
i don't know
Step-by-step explanation:
Let's say the savings in your account are given by $V, the number of weeks by n and the starting balance by $x:
V = x + 200n
Now if after saving for 4 weeks you have $1700 in your account, then:
1700 = x + 200*4
1700 = x + 800
x = 900, thus your starting balance is $900
Using this information we can now write up the general equation for the savings at the end of each week:
V = 900 + 200n
Anything that has an equla sign would be considered a function.
In this case i would say that everything that has P is equal to would be function, and everything that has a percant sign would be weekly growth rate.
Hope that helps!!!

The answer is -10.
Remember the rule:
A positive times a positive is a positive
A negative times a positive is a negative
A negative times a negative is a positive
Thus, the answer is -10.
Hope it helps! Enjoy your day!
