Colin had an average of 96% on his statistics tests going into the last test. He didn’t take the last test and his grade fell to 80%. Assuming each test is worth the same number of points, how many tests were there, including the test Colin didn’t take?

If he took x tests, then
96x = 80(x+1)
96x = 80(x+1)
