Answer:
5x and 6x both have the letter x. Let's combine them! 5x+6x = 11x
y, y, and 3y all have the letter y. You can imagine y to be 1y, they're the same.
1y + 1y + 3y = 5y
4, 6, and 2 don't have any letters. 4 + 6 + 2 = 12
Now you have to put all the final terms together to get: 11x + 5y +12

Answer:
$280.51
Step-by-step explanation:
The formula we want to use:
where:
P is the principal
r is the the rate
n is the number of compounding per year
t is total number of years
A is the ending amount
We are given P=200, r=.07, n=1 (compounded once a year), t=5.
So plugging this in:
Simplify a little:
Just a little more:
Now I'm going to put the rest of this in the calculator:
200*(1.07)^5 is what I'm putting in my calculator.
This is approximately 280.5103461.
To the nearest cent this is 280.51
