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
calendars.

Y=2.50x + 500

10. Each calendar will sell for $5.00
each. Write an equation to model the
total income, y, for selling x
calendars.
