Mei is looking for a job cutting hair. One option is self-employment at The Richmond Salon, where she would pay $639 per month to rent a station and keep all of her earnings. Another option is to work at a franchise, where she would just have to pay the salon $9 for every haircut.

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
