Question

Elliott has some yarn that she will use to make hats and scarves. Each hat uses 2 yards of yarn and each scarf uses 3 yards of yarn. Elliott has a total of 22 yards of yarn, and she wants to make a total of 9 items. Let h be the number of hats Elliott makes and s be the number of scarves she makes

Answer 1

s = 4

h = 5

Explanation:

2*h + 3*s =22

h + s = 9

h = 9 - s

2(9 - s) + 3s = 22

18 - 2s + 3s = 22

18 + s = 22

s = 22 - 18

s = 4

h + s = 9

h + 4 = 9

h = 9-4

h = 5
