Mark is a teaching assistant at a local community college. a tutor at the college works the same number rod hours as mark but earns $11,700 less annually. the sum of marks and the tutors annual salary is $99,000. how much did each earn?

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
