Erika calculated that she would spend $115 on school supplies this year. She actually spent $82.50 on school supplies. What is Erika’s percent of error? 28.3% 2.8% 39.4% 32.5%

dukedadon:

divide 115 by each percent (:

dukedadon:

cd and D are not correct so that leaves us with A and B

dukedadon:

B is too small to even logically be reasonable, so once you divide 115 by each percent your answer would be 28.3 % (:

QueenMidnight16:

thank you

surjithayer:

difference=115-82.50=32.50 percentage error\[=\frac{ 32.50 }{ 115 }\times100\]\[=\frac{ 3250 }{ 115 }\]\[\approx28.26 \approx 28.3\]

dukedadon:
