The science club sells T-shirts for $10 each and key chains for $2 each in a fundraiser with a $500 goal. How many T-shirts and key chains could they sell to meet or exceed their goal?

20 tshirts and 150 keychains

Step-by-step explanation:

let tshirts be 10x and keychains be 2y

now make a Quadratic equation,

10x+2y=500

=let x = 20

=(10×20)+2y=500

=200+2y=500

=2y=300

y=300/2 = 150

therefore 20 tshirts and 150 keychains sumsup their goal of 500 dollars
