Andy estimated that he would need 72 feet of lumber for a tree house project. he later found that the actual amount of lumber needed was 61 feet. what was the percent error of andy's estimation? a. 15.28% b. 84.72% c. 18.03% d. 11%

72x = 61

x = 61/72

x = 84.72%

100 - 84.72 = 15.28

Option A.

The percent error of Andy's estimation is 18.03%.

x^6

step-by-step explanation:

this is correct because:

x-6=0

0*x=0

so

x^6

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get
