The price of commodity a is 4500 and increases at the rate of $6 every three months. commodity b costs $5400 and increases at rate of $2 every four months. how many years will it take for the two commodities to be equal?

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.
