Question

The math club is doing a fundraiser to raise money 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 "i like TT" sweaters for $20. let x equal the number of T-shirts sold and let y equal the number of sweatshirts sold.
Are the graphs of the equations parallel and how can you tell?

Answer 1

Answer:

number of t-shirts are represented by 't'  

number of sweaters are represented by 's'

Step-by-step explanation:cost of 1t=10 and cost of 1s=20 so

10t+20s=2000 or (factor out the 10 if you optate to simplify)

10(t+2s)=10(200)

divide both sides by 2

t+2s=200
