Kaelyn has some yarn that she wants to use to make hats and scarves. Each hat uses .20, point, 2 kilograms of yarn and each scarf uses 0.10, point, 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? Choose 1 answer:

Answer 1

Answer:

s = 3h

0.2h + 0.1s = 5​

10 Hats

30 Scarfs

Step-by-step explanation:

h  be the number of hats Kaelyn makes

Each hat uses 0.2 kg  of  yarn

so total yarn used in Hats= 0.2h  kg

s be the number of scarves she makes

Each scarf uses = 0.1 kg of yran

so total yarn used in scarfs = 0.1s

0.1s + 0.2h  = 5

s = 3h

=> 0.3h  + 0.2h = 5

=> 0.5h = 5

=> h = 10

10 Hats

30 Scarfs
