The percent increase is

.

78%

.step-by-step explanation:

first determine how much it increased by. 36+X=64

X=28

it increased by 28

now determine what percentage 28 is of 36

36(Y)=28

Y=.77777778

28 is a 77.78% (.7778) increase from 36

after you round, your answer is 78%

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
