Kaelyn has some yarn that she wants to use to make hats and scarves. Each hat uses 0.2 kilograms of yarn and

each scarf uses 0.1 kilograms of yarn, Kaelyn wants to make 3 times as many scarves as hats and use 5
kilograms of yarn.
Let h be the number of hats Kaelyn makes and s be the number of scarves she makes
Which system of equations represents this situation?

using 5 kilograms of yarn Kaelyn can make 16 (or) 17 hats and 16 (or) 17 scarfs and

5.55 times available to fulfill her wish of making 3 times as many scarves as hats using 5 kilograms of yarn.

Step-by-step explanation

Let

h be the number of hats uses 0.2 kilograms of yarn

s be the number of scarves uses 0.1 kilograms of yarn

The equation will be = 3h + 3s ≤ 5 kilograms

= 3(0.2) + 3(0.1) ≤ 5

= 5 ÷ 0.6 + 0.3


= 3h + 3s ≤ 5 kilograms = 3(0.2) + 3(0.1) ≤ 5 = 5 ÷ 0.6 + 0.3

= 5 ÷ 0.9 = 5.55 times when Kaelyn wants to make 3 times as many scarves as hats

Number of hats = 5.55×3 = 16.65 ≤17 hats


Number of hats = 5.55×3 = 16.65 ≤17 hats

Number of scarfs = 5.55×3 = 16.55 ≤ 17 scarfs


Number of scarfs = 5.55×3 = 16.55 ≤ 17 scarfs

using 5 kilograms of yarn Kaelyn can make 16 (or) 17 hats and 16 (or) 17 scarfs and

5.55 times available to fulfill her wish of making 3 times as many scarves as hats using 5 kilograms of yarn.
