Answer 1

@horsegirl325 @campbell_st @Nnesha

Answer 2

difference in scores/actual score x 100

the interesting thing is that appears rounding has been ignored in the solution

Answer 3

please help me? Is it B,C, or D? @campbell_st

Answer 4

@GretaKnows

Answer 5

Okay so @campbell_st was right. what you need to do is find the difference between the two scores

Answer 6

which is 12 then divide 12 by 152

Answer 7

0.07894736842

Answer 8

Yes now you need to turn it into a percent. move the deciaml point twice to the right

Answer 9

7.8?

Answer 10

well 7.89. since 9 is more than 5 you have to round up. so 7.9

Answer 11

so it's 7.9? one person told me it's 12% and someone else told me it's 8.6 so are you sure?

Answer 12

im pretty sure you can check your answer by multiplying each percentage, be sure to make them into deciamls by moving the deciaml point, by 140 and seeing which one is closest to 12
