Idk how to do this, i need the work and answer .

One way you can solve this is with a proportion it is set up like this

on the top you have the test and the x represents the test we are trying to find. on the bottom is the number of weeks that you've taken. first you will have to do 5 times x. and then 10 times seven then you will end up with a set up like this

next you will divide both sides by 5. ( you always divid by x) and what you do on one side you have to do on the other. 5x divided by 5 is x and 70 divided 5 is 14. so your answer will be

I hope you understand

It is a percent with money involved too divide and you should have your answer

If your asking how much altogether for 12 performance the answer will be 98,496.
