In a certain clothing store, 3 shirts and 5 ties cost $60, and 2 shirts and 3 ties cost $39. What is the cost of each shirt?

Dovator [93]

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

The ratio of 10 to pencil is 2/7 if you count 84 pencil how many pain would you expect to find

frosja888 [35]

How much pain would you find? hopefully none, since you'd have lots of pens and pencils :).

$\bf \cfrac{pens}{pencils}\qquad \cfrac{2}{7}\qquad 2:7\qquad \qquad \cfrac{\stackrel{pens}{p}}{\stackrel{pencils}{84}}=\cfrac{2}{7}\implies p=\cfrac{84\cdot 2}{7}$
