Question

Joy sells two types of yarn: wool and synthetic. Wool is $12 per skein and synthetic is $9 per skein. If Joy sold 16 skeins of synthetic and collected a total of $432, how many skeins of wool did she sell?

Answer 1

Answer: Joy sold 24 skeins of wool.

Step-by-step explanation:

First you have to see how much of the money she has total came from the synthetic yarn profit.

If she sold 16 skeins of synthetic yarn you multiply 16 x 9(the price per skein of synthetic yarn) to get 144.

Next you subtract 144 from 432 (432-144) to get 288.

Finally, divide 288 by 12(the price of a skein of wool yarn) to get 24.

24 is the amount of skeins of wool yarn she sold.

To be sure you can multiply 24 x 12 (wool yarn sold) and add that to 16 x 9 (synthetic yarn sold) to get 432 which is your total profit.

Hope this helps!

Answer 2

Answer: 24
multiple the amount of synthetic skeins sold to the price of one synthetic skein. subtract the sum to the total. take the subtracted sum and divide it by the price of wool skeins
