Allison's average score on four tests is 65.
If her lowest score is left out, her average score for the three remaining tests would be 69.
What is Allison's lowest score
:
let x = her lowest score
we can assume the score, on the other 3 tests, is 69
%28x%2B3%2869%29%29%2F4 = 65
%28x%2B207%29%2F4 = 65
multiply by 4
x + 207 = 4(65)
x = 260 - 207
x = 53 was her lowest score
