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:
Step-by-step explanation:
a-5 = -5+a
m-n = m + (-n)
7+3 = 7 - ( -3)
a+5 = a - (- 5)
a+b = a - (-b)
I think it is either 4.41 or 1.84 Sq Ft
