Let p = the price of one pair of pants and t = the price of one t-shirt. Which equation is needed to represent the situation?
Cathleen purchased a pair of pants and three t-shirts and spent a total of $54 before taxes. If she spent an equal amount of money on the one pair of pants and the three t-shirts, how much does each t-shirt cost? Assume all the t-shirts are the same price.
A) t = 3p
B) p + t = 54
C) p + t = 18
D) p + 3t = 54
