You need to buy 5 shirts. you see one shirt for $8.25, but a competitor's brand is 8 shirts for $70. you do not need to buy all 8 shirts to get the sale price. which brand is the cheapest, and how much will you spend on the 5 shirts with this cheapest brand?

The brand that sells each individual shirt for $8.25. You will only have to spend $41.25 if you that way for five shirts and for 8 shirts you would only spend $66 when the competitor would have you pay 70$ for 8 shirts.

Step-by-step explanation

First: Multiply $8.25 by five and you'll get $41.25.

Second: Multiply $8.25 by 8 and you'll get $66.

Therefore it is cheaper to buy from the first company. Not the competitor.

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.
