(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
