Step-by-step explanation:

Hello, great question. These types are questions are the beginning steps for learning more advanced Algebraic Equations.

Since we have two different values for two different years, we can use the following Algebraic Expression to calculate the percent difference of sales between both years. The Expression would be the following,

Where x is the percent difference. Now we solve for x,

so now we see that the percent of Increase is of 11.08% (0.1108)
