Question

A baseball club pays a vendor $135 per game for selling bags of peanuts for $4.25 each. (a) Write a linear function that describes the profit p the vendor makes for the baseball club during a game if she sells b bags of peanuts.

Answer 1

A linear function is a numerical relationship that forms a straight line in the Cartesian plane and represents the number of units that change a dependent variable, increase or decrease, compared to an independent one, in this case the profit P of the baseball club will be given by the number b of peanut bags sold multiplied by the sales value ($4,25), this less the payment of the seller's work day ($135), that is:

`P = $4.25 b-$135`

Answer

The linear function that describes the profit of the baseball club is

`P = 4.25 b-135`
