Question

On three tests, a student scored a total of 258 points. If the student improved his performance on each test by 5 points, what was the score on each test?

Answer 1

x+(x+5)+(x+10)=258

3x=243

x=81

 

test scores are

81, 86, 91

 

add these together to check your work

81+86+91=258

 

hurrah!
