dukedadon · Answer

divide 115 by each percent (:

dukedadon · Answer

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

dukedadon · Answer

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

thank you

surjithayer · Answer

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