Coach Wilson ordered T-shirts for the basketball team from two different T-shirt suppliers. One supplier charged $16 for each shirt, as well as 5% for shipping. The other supplier charged $18 for each shirt, plus 7% for shipping.

Part A

Coach Wilson ordered the same number of shirts from each supplier. Write an equation to find the shipping charges he paid to each supplier.

Part B

The first supplier gave Coach Wilson a discount of 10% off of his order total. The second supplier gave him a discount of $20 off of his order total. Write an equation to find the total cost, T, of the shirts.

Part C

Coach Wilson ordered 15 T-shirts from each supplier. How much did he pay?

Part A:

# of shirts bought in total (T) times cost of each shirt (E) = X. X times. 5 (same as 5%) = shipping charge (S) =

first: T*E=X. second: X*.5=S

Part B:

vendor 1:

# of shirts bought (A) times cost of each shirt (B) plus shipping charge (C) times 10%=T. A*B+C*.10=T

vendor 2:

# of shirts bought (A) times cost of each shirt (B) plus shipping charge (C) minus $20 = T. A*B+C-20=T

Part C:

vendor 1:

15*16=240 (total # of shirts * cost of ea.)

240+8 = 248 (1st answer + $8 of shipping)

248*.10 = 24.80 (2nd answer * 10% discount)

248-24.80 = [223.20] (2nd answer - 10%)

vendor 1 total cost: 223.20.

vendor 2:

15*18=270 (# of shirt bought * cost of ea.)

270+12.60=280.60 (answr 1 + shipping cost)

280.60-20=[260.60] (answr 2 - $20discount)

vendor 2 total cost: 260.60.
