Question

hector and jeremy want to make some cd's for their band, goat cheese pizza. jeremy figures it would cost 399.00 to produce 1,000 cd's hector figures it would cost 54.25 to produce 15 cd's they are both correct. you are going to write an equation to find the cost of producing cd's help me

Answer 1

This can be solve by using linear equation. Let y be the cost to produced and x be the number of cd’s. so let point 1 be ( 1000, 399) and point 2 to be ( 15, 54.25). then solve the slope

M = (y1 – y2)/ (x1 – x2) = ( 399 -54.25)/ ( 1000 – 15) = 0.35 cost per cd

Y = mx + b

399 = 0.35(1000) + b

B = 49

Y = 0.35x +49 is the equation
