Question

Chevy has some yarn that he wants to use to make hats and scarves. Each hat uses 0.20.20, point, 2 kilograms of yarn and each scarf uses 0.10.10, point, 1 kilograms of yarn. Chevy wants to use 222 kilograms of yarn to make a total of 151515 items.
Let hhh be the number of hats Chevy makes and sss be the number of scarves he makes.
Which system of equations represents this situation?

Answer 1

h + s = 15 & 0.2h + 0.1 s = 2 , 5 Hats & 10 Scarves

Step-by-step explanation:

Each hat uses  0.2 kg of Yarn

Each scarf uses  0.1 kg of Yarn

Total item = 15

h number of hats

s number of scarfs

h + s = 15    Eq1

Yarn used = 0.2h + 0.1s  

0.2h + 0.1 s = 2

multiplying by 10

2h + s  = 20   Eq2

Eq 2 - Eq 1

= h = 5

  5 + s = 15

=> s = 10

5 Hats & 10 Scarves
