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)
