Selena is baking chocolate chip cookies. The recipe calls for 2 cups of chocolate chips. If she has already put in 1 cups into the batter how many
more cups of chocolate chips should be added to the batter

Well 1 more cup of chocolate chips since she already put one cup and she needs 2 cups?

1 more cup

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.
