Question

The small manufacturer pays $1300 each month for site rental and it costs $3.00 to produce each of the widgets. What's the total cost for the the small medical company each month as it varies the number of plastic widgets produced?

Answer 1

The problem provides the following:

1) the rental cost is $1300/month

2) the cost per widget manufactured is $3.00/widget

The question is looking for the total cost to a manufacture the widgets.

Let w = the number of widgets made in a month.

Let C = Total Cost;

The total cost for the month would be the rental cost plus the cost of the widgets.

C = $1300 + ($3.00/widget)*w
