Question

Sarah bought 10 skeins of yarn for $27.50 to knit a baby blanket. The white yarn cost $3.50 each, and the pink yarn cost $2.25 each. How many skeins of each color did she buy?

5 white and 5 pink
6 white and 4 pink
5 white and 4 pink
4 white and 6 pink

Answer 1

Hi there:)

2.25x+3.5 (10-x)=27.5
Solve for x to find the number of pink yarn
2.25x+35-3.5x=27.5
2.25x-3.5x=27.5-35
-1.25x=-7.5
X=7.5÷1.25
X=6. Pink

10-6=4 white

Hope it helps
