Tony and Kurt get the same salary. Every month Tony saves
9
11
of his salary while Kurt saves
7
of his salary. Every year Tony saves $1344 more than Kurt. Find the monthly salary of Tony.
Tony saves 1344/12 = $112 per month more than Kurt
So....let x be the monthly salary for both
So
(9/11) x = (7/9)x + 112 multiply through by 99
81x = 77x + 11088 subtract 77x from both sides
4x = 11088 divide both sides by 4
x = $2772 = monthly salary for both
