Candice bought 3 shirts. each shirt cost the same amount and was discounted by $3.66.candice paid a total of $62.31 before tax. how much did each shirt cost before the discount?

Let the cost of each shirt be x.

Would assume each  shirt was discounted by 3.66

Amount to be paid for each :    x - 3.66

Total =    3*(x - 3.66)

3*(x - 3.66) = 62.31

x - 3.66 = 62.31/3

x - 3.66 =  20.77

x = 20.77 + 3.66

x = 24.43

Each shirt cost $24.43  before the discount. 

I'm pretty sure it's b). i try drawing the functions out and b is the one that stands out or isnt a "line"
