Respuesta :
x + y = 23
10x + 12y = 246
[tex]x = 23 - y[/tex]
Put that into
[tex]10(23 - y) + 12y = 246 \\ 230 - 10y + 12y = 246 \\ 2y = 16 \\ y = 8[/tex]
Substitute that into
[tex]x = 23 - 8 \\ x = 15[/tex]
They sold 15 t-shirts and 8 hats.

Answer with Step-by-step explanation:
Let number of t-shirts=x
and number of hats=y
Basketball team sell t-shirts and hats as a fundraiser they still hold a total of 23 items
⇒ x + y = 23
They made a profit of $246, they made a profit of $10 for every t-shirt and $12 for every hats they sold
⇒ 10x + 12y = 246
Putting x = 23 - y in above equation, we get
⇒10(23 - y) + 12y = 246
⇒230 - 10y + 12y = 246
⇒2y = 16
⇒ y = 8
Substitute that into
x = 23 - 8 , we get
x = 15
Hence,they sold 15 t-shirts and 8 hats.
