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.

The answer is b: step 2.
