Question 846346
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
{{{(x+3(69))/4}}} = 65
{{{(x+207)/4}}} = 65
multiply by 4
x + 207 = 4(65) 
x = 260 - 207
x = 53 was her lowest score
