A school is selling t-shirts and sweatshirts for a fund-raiser. Sally sold 2 t-shirts and 2
sweatshirts for a total of $38. Treya sold 3 t-shirts and 1 sweatshirt for a total of $35. How
much does each t-shirt and sweatshirt cost?

Answer:

T-shirt costs $28. Sweatshirt costs $11.

Step-by-step explanation:

let t = cost of a t-shirt and s = cost of a sweatshirt

2t + 2s = 38

3t + s = 35

3t+s-2t-2s = 35-38

t-s=-3

3t+s+t-s=32

4t=32

t=8

s = 11
