I kind of guessed 163 but I cant do the problem I keep getting a decimal but my multiple choice doesn't have decimals in the answers
jigglypuff314 (jigglypuff314):
what is the average of 14 and 20?
(14+20) divided by 2 =
OpenStudy (anonymous):
24
jigglypuff314 (jigglypuff314):
then times 8
jigglypuff314 (jigglypuff314):
no. wait...
(14+20) = 34
34 / 2 = 17
