This is the concept of algebra, to calculate the proportion of wool in each item we proceed as follows;
Let the amount of wool used for hat be x
amount of wool in sweater will be 5x
the amount of wool used in scarf will be x-5
therefore the total amount of wool will be:
x+5x+(x-5)=550
x+5x+x-5=550
7x-5=550
7x=550+5
7x=555
hence;
x=555/7
x=79
the amount used in hat x=79g
amount used in sweater 5x=395g
amount used in scarf=79-5=74g

Hello!
Add up the costs of everything Kyle purchased and the tax, and then subtract that from $10.
4.95 + 2.30 + 1.10 + 0.65 = 9
10 - 9 = 1
Kyle should have received $1 change.
