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.
$?

-2.75r+5r=p

and 900 for the profit and second part of the question.

Step-by-step explanation:

So first to solve this you need to plug in 400 for r

-2.75*400+5*400=p

you are then going to solve the -2.75*400

you get -1,100

you then are going to do the second part of the equation

yo get 2000

-1,100+2000 to get your profit of 900

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
