A grocery store sells a bag 7 oranges for $2.66. if alexandra spent $3.42 on oranges how many did she buy

9 oranges

Step-by-step explanation:

7 for 2.66 is 38c for 1

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.
