Question

The highest score on an Algebra test was 40 points more than the lowest. When added together, the lowest and highest score was 152. Write an equation to find the highest score, then solve.

*
x + x + 40 = 152; 56
x + x + 40 = 152; 96
x + x = 152; 76
x + x - 40 = 152; 96

Answer 1

Answer: x + x - 40 = 152; 96

Explanation:

If x is the highest score, then x - 40 would be the lowest score because of a 40 point difference. Adding these terms would result to x + x - 40 which is equal to 152. This sets up the equation x + x - 40 = 152. The value of x in this equation would be 96.
