Answer:
s = 3h
0.2h + 0.1s = 5
10 Hats
30 Scarfs
Step-by-step explanation:
As given in the question, h = the number of hats Kaelyn makes and s = the number of scarves she makes.
Hat = 0.2 kg of yarn
Therefore, yarn used in Hats = 0.2h kg
Each scarf = 0.1 kg of yarn
Yarn used in scarfs = 0.1s kg
i. 0.1s + 0.2h = 5
ii. s = 3h
Substituting equation ii into i,
0.3h + 0.2h = 5
0.5h = 5
= 10
Therefore, scarf, s = 3 * 10
= 30
10 Hats
30 Scarfs
