Step-by-step explanation:

First divide 720 by 8 which equals 90 so each book cost 90 dollars which is dub

if you explain the the question more correctly i might be able to answer this better

step-by-step explanation:

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
