Fashion phreddy buys 5 shirts and 3 ties for 91 on the bargain bus. billy joe bob buys 8 shirts and 5 ties for 146. if all the shirts sold for the same price and each ties were priced identically. how much was each shirt and tie.

Assume that the price of the T-shirt is x and the price of the tie is y.

Fashion Phreddy buys 5 shirts and 3 ties for 91. This means that:
5x + 3y = 91 > equation I
5x = 91-3y
x = 18.2 - (3/5) y > equation II
Billy joe bob buys 8 shirts and 5 ties for 146. This means that:
8x + 5y = 146 > equation III

Substitute with equation II in equation III:
8(18.2 - (3/5) y) + 5y = 146
145.6 - 4.8y + 5y = 146
0.2y = 0.4
y = 2
Substitute in equation II to get the value of x:
x = 18.2 - (3/5) (2) = 17

Based on the above calculations:
price of T-shirt = x = 17
price of tie = y = 2
