Find the percent increase. Round to the nearest percent. From 95 books to 139 books.

The percent increase is __%

(I just need the answer, no need for explanation)

Suredude why not right

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
