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.
Answer:
x+63°+36°=180°(angle sum property in first triangle)
x+99°=180°
x=180°-99°
x=81°
x + z=180
81°+z=180°
z=180°-81°
z=99°
z+13°+y=180(angle sum property in second triangle)
99°+13°+y=180
112°+y=180°
y=180°-112°
y=68°
therefore, x=81° z=99° y=68°
