PLEASE PLEASE PLEASEEE HELP ME Jamal needs to purchase a countertop for his kitchen. Jamal measured the countertop as 5 ft. The actual measurement is 4.5 ft. What is Jamal’s percent error?
A) 5%
B) 11%
C) 45%
D) 50%

percent error is 11.1%  (which agrees with answer B)

Step-by-step explanation:

The discrepancy (difference) between the measurement and the real length was: 5 - 4.5 = 0.5 ft

Then the percent difference is calculated as:

(difference / real value) * 100 = ( 0.5 / 4.5ft  ) * 100 =  11.1%

B). 11%

Step-by-step explanation:

0.5/4.5 = 0.11 * 100 = 11

The 0.5 represents the difference between the actual measurement and Jamal's measurement. Dividing it by 4.5 then multiplying the answer by 100 determines what % of 4.5ft 0.5ft is. 0.5ft is 11% of 4.5ft meaning that Jamal's measurement is 11% off
