Each band member is selling wrapping paper to help raise money for the band banquet. The band pays $2.75 for each roll of wrapping paper.

The rolls are then sold for $5.00 each.

Write an equation to find the profit for any amount of rolls sold. Use p for total profit and r for the number of rolls of wrapping paper.

Solve your equation to find the total profit the band members make if they sold 400 rolls.
$?

Should be 900 total dollars profit. If they bought 400 rolls, for $2.75 it would come out to be $1,100. Then selling them for 5 each would make the total amount made equal to $2000, subtract the amount spent, and the total profit is $900. So p = 900. Now we have to find R, so if we spent a total of $1,100 on selling the wrapping paper divide that number by the amount that it cost to buy them. And R = 400. I think lol
