Answer: 8.8% decrease to the nearest tenth
Step-by-step explanation: For this problem we will be finding the percent decrease, so we could write a "percent decrease" equation.
change = percent change x original amount
To find the change subtract, 80-73, which equals 7
7 = percent change x original amount
The original amount is 80 because it is the number before being decreased.
7 = percent change x 80
Solve for p, percent change.
7 = p x 80
7/80 = p
0.0875 = p
To find the percent change multiply 0.0875 by 100 to get a percent.
0.0875 x 100 = 8.75% percent decrease.
8.75% to the nearest tenth is 8.8%.
