Zahra is knitting items to sell at a craft fair. She has a total of 2,640 yards of yarn. A scarf uses 200 yards of yarn, and a hat uses 150 yards. She wants to knit a minimum of 15 items.

This system of inequalities represents this situation, where x is the number of scarves and y is the number of hats.
200x + 150y ≤ 2,640
x + y ≥ 15

How many scarves and hats can she make?

What is 5 scarves and 10 hats?
