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 equation Ax + By = C $4740 $15 $60 60x + 15y = 4740
Find the x and y intercepts of this equation 60x + 15y = 4740 How to find the x intercept How to find the y intercept 60(0) + 15y = 4740 60x + 15(0) = 4740 15y = 4740 60x = 4740 x = 79 y = 316 (0, 316) (79, 0)
2 Y 2 The y intercept is at (0, 316) 300 250 200 150 100 50 0 This means they can sell 0 print yearbooks and 316 yearbooks to earn the $4740 they want Digital yearbooks 2w The x intercept is at (79, 0) This means they can sell 79 print yearbooks and 0 yearbooks to earn the $4740 they want 0 20 40 60 80 100 X Print yearbooks
