Laura spent ⅕ of her money on a new pocketbook and had $90 remaining. How much did she spend on her new pocketbook?

$18

Step-by-step explanation:

90 x 1/5

90/5

18

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
