Answer: 35% decrease
Step-by-step explanation: In this problem, we're asked to find the percent decrease if the price of an item changes from $180 to $117.
To find the percent decrease, we use the following formula.
![\frac{amount of change}{original number}](https://tex.z-dn.net/?f=%5Cfrac%7Bamount%20of%20change%7D%7Boriginal%20number%7D)
The <em>amount of change</em> is the difference between the two numbers which in this case is 180 - 117 and the <em>original number</em> is the first number which is 180.
The difference between 180 and 117 is 63 and we put that over 180.
Now we have
.
Now, we either use a calculator or long division. I will use my calculator but if you don't have access to one, long division is always available.
63 ÷ 180 = 0.35
Now since we want to find the percent increase, we need to change 0.35 to a percent and we can do this by moving the decimal point two places to the right.
0.35 ⇒ 35%
So when the price changes from $180 to $117, it is decreased by 35%.

Step-by-step explanation:
f(x) = 5x - 20
f(-1) = 5(-1) - 20 = - 5 - 20
= - 25
g(x) = x² + 5x - 11
g(2) = 2² + 5(2) - 11 = 4 + 10 - 11
= 3
Thus, f(-1) + g(2) = - 25 + 3 = - 22
