Question

A person must score st least 360 points to make an A in one of the classes. If they currently have the scores of 82,91, and 89 points from her first three tests, how many more points does she need to make an A ?

Answer 1

To solve this you first add 82, 91, and 89. Then you will subtract that total from 360 to get you answer.
 91 + 89 + 81 = 262
360 - 262 = 98

Answer 2

$82+91+89=262$
$360-262=x$
Solve for $x$
