Annika is selling art prints at a comic convention.The convention charged her $50 for her table space, and she is selling her prints at $2 each.Write an equation to represent the net profit Annika makes from sell a prints, and then determine how many prints she need to sell if she wants to make $130.How many prints will she need to sell per day if the convention runs from Friday to Sunday.Show your work.

Answer 1

2x-50=130
     +50  +50
2x=180
/2     /2
x=90
She will need to make $90

Answer 2

Lets set up our values first:

She starts out with -50 because of the table charge.

Then she earns $2 per print written as 2x

Her net profit will be y and the equation is as follows:

2x - 50 = y

------------------------

Now she wants a profit of $130 so we set y = 130

2x - 50 = 130

Solve:

2x = 180

x = 90

-------------------------

She is there for a course of 3 days so we jist divide the amount by 3:

90 / 3 = 30 prints a day
