Mauldin Middle School wants to make $4740 from yearbooks. Print yearbooks
(x) cost $60 and digital yearbooks (y) cost $15. Write and equation to represent
this information.
Standard form of an equationAx + By = C
$60 $15 $4740
60x + 15y = 4740
Find the x and y intercepts of this equation
60x + 15y = 4740How to find the
x interceptHow to find the
y intercept
60x + 15(0) = 4740 60(0) + 15y = 474060x = 4740 15y = 4740
x = 79 y = 316(79, 0) (0, 316)

The y intercept is at (0, 316)
This means they can sell 0 print
yearbooks and 316 yearbooks to earn
the $4740 they want
The x intercept is at (79, 0)
This means they can sell 79 print
yearbooks and 0 yearbooks to earn
the $4740 they want
