Prices changed from 100% price to 80% price due to sale.
100% - 20% = 80%
THEN increased by 25% so
80% + 25% = 105%
so the overall effect is that the price rose from the original (100%) to 105%
so a 5% increase
35% was damaged.
1 percent is 400 acres, so 14000/400= 35% of forest was burned
Answer:

divide by 100:
x=24
Not quite sure how you want me to explain the other way step by step... Hope this helps!
80*.3=24
The value of y when x equals -15 in the equation (y = - 180 - 9(x)) is -45.

In a given function y = f(x) = bx - c, the value of y can be determined, if the value of x is known. All we have to do is to substitute the known value for x into the equation in order to determine the value of y.
From the given information:
y = - 180 - 9(x)
y = -180 - 9(-15)
y = -180 + 135
y = -45
