Corey had 20 dollars to spend on 3 gifts. he spent 8 9/10 dollars on gift a and 6 3/5 dollars in gift b. how much money did he have left for gift c?

I believe he had $4.50 left for gift c

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.

answer: 2530

hope this
