Answer:
C.
Step-by-step explanation:
Looks like C ( if the polynomial in the question contains x6 NOT x).
First you have to divide 45 by 16. that gives us 2.8125. then multiply 2.8125 by 80 to get 225.
Let shirts be x and ties be y
3x+5y=$60 Equation 1 (Equation 1 will be denoted by *)
2x+3y=$39 Equation 2 (Equation 2 will be denoted by !)
*x2 6x + 10y = $120
!x3 6x + 9y = $117
*-! y = 120-117 =3
Ties are $3 each
Substitute this value back into one of the original 2 equations:
3x+5y=$60
3x+(5x3) = 60
3x+15=60
3x=45
x=15
Shirts are $15
Answer:2/3 x 15 = 10
1/4 x 5 = 1.25
2 1/2 x 1/7 = 5/14
