Question

A plant can manufacture 30 tennis rackets a day for a daily cost of $2100 and 50 rackets a day for $3000. Let y represent the cost and x represent the number of rackets. How much more does it cost to produce 31 than 30 rackets per day?

Write your equation in the slope intercept format. Show all your work, make a graph, and turn it into me.

Answer 1

I'm not a magician; I can't turn it into you...

assume y = mx+b
2100 = 30m + b
3000 = 50m + b

900 = 20m
m = 45
b = 750

So, it costs $45 to produce a racket.
Must be a fine for the noise made producing racquets...
