#### Work Step by Step

We can use the following guideline to solve this problem.
Current number of stores + Increase in the number of stores = Number of stores after the increase
So, 50 + 40% $\times$ 50 = Number of stores after the increase
50 + .4 $\times$ 50 = Number of stores after the increase
50 + 20 = Number of stores after the increase
70 = Number of stores after the increase
There will be 70 stores in the Orlando area after the increase.
