During one school year, Billy Bob earned $25 for each Math test he passed and was ined $50 for each Math test he failed. By the end of the school year, Billy Bob passes 7 times as many Math tests as he failed and he had a total of $375. How many tests did he pass?

Failed X tests.
Passed 7X tests.

25*7X - 50*X = 375,
175X - 50X = 375,
125X = 375,
X = 3 Tests failed.

7x = 7*3 = 21 Tests passed.
