Cameron is designing a calendar as a fund raising project for math class. The cost of printing is $500, plus $2.50 per calendar. Write an equation in slope intercept form that models the total cost of printing the calendar. Each calendar will sell for 5.00 each. Write an equation to model the total income , y , for selling x calendar

In the first equation, x represents the number of calendars printed and y represents the total cost. Each calendar costs $2.50 to print; this gives us the expression 2.50x. We also have the $500 fee for printing, which gives us 2.50x + 500. This is the total cost of printing, which is represented by y:

y = 2.50x + 500

For the second equation, x is the number of calendars sold and y is the total income. Each calendar sells for $5; this gives us 5x. However, we must take away the cost of printing. We already know from the previous equation that the expression for the cost of printing is 2.50x+500; we take this away from 5x and have

y = 5x-(2.50x+500)

Distributing the subtraction sign, we have

y = 5x-2.50x-500

Combining like terms, we have

y = 2.50x-500

The equations for modeling the total income is y = 2.50x + 500 and y = 2.50x - 500.

Given that,

There is a printing cost of $500 plus $2.50 per calendar.
Each calendar should be sold at $5.00 each.

Based on the above information, the equations are as follows:

y = 5x-(2.50x+500)

y = 2.50x + 500

And, y = 2.50x-500

Therefore we can conclude that the equations for modeling the total income is y = 2.50x + 500 and y = 2.50x - 500.
