PLEASE HELP QUICK!! Steve's bill at a restaurant for lunch was $15. He had exceptional service and wanted to leave a 20% tip for his waiter. What is the total cost of his lunch?
A$3
B$15
C$18
D $5

C) $18

Step-by-step explanation:

20% of 15 is 3. That is how you get your tip. If you add the $3 tip to the $15 meal, your meal costs $18.

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.
