Question

The math club is doing a fundraiser to raise money for to attend a math competition. The club was told by their advisor to raise $2000, but they decided to raise $4000. The club is selling" I like TT" t shirts for $10 and sweatshirt for $20 let x equal the number of t shirt sold and let y equal the number of sweatshirt sold

Answer 1

number of t-shirts are represented by 't'
number of sweaters are represented by 's'

cost of 1t=10 and cost of 1s=20 so
10t+20s=2000 or (factor out the 10 if you want to simplify)
10(t+2s)=10(200)
divide both sides by 2
t+2s=200
