Clarence has a certain sum of money. He needs an extra $44 in order to buy

3 jerseys. After receiving $108 from his father, he is able to buy 5 jerseys.

(a)   How much is the cost of one jersey?

(b)   How much money does Clarence have at first?  

 

Let X be the original certain sum of money  

 

X + 108 = 5 jerseys  

X +   44 = 3 jerseys     now subtract this one from the one above   

 

        64 = 2 jerseys  

        32 = 1 jersey      This is the cost of one jersey  

 

Plug the value of J back into one of the first equations  

 

X + 108 = 5 • 32  

X + 108 = 160  

          X = 52               This is how much money he had to start with
