Question

A printer charges $3.00 for binding plus 5 cents per page for each copy of a community group's annual report.

Write the cost equation and answer the following questions.

What is the fixed cost?

What is the variable cost?

Let y represent the cost of the annual report and x represent the number of pages.

What is the cost equation? y =

What will it cost to produce a 28 page report?

If the report cost was $6.50, the report is __ pages.

Note: I don't know the cost equation for this.

Answer 1

Fixed Cost = cost to use the printer (regardless of how much you actually print)

Variable Cost = cost per page

Answer 2

So in this case,

Fixed Cost = $3

Variable Cost = $0.05

Answer 3

The cost equation is then...


Total Cost = (Variable Cost)*(Number of Pages) + Fixed Cost

if y is the total cost to print x pages, then,

y = 0.05x + 3

Answer 4

The other parts will have you use the cost equation

In the next part, you plug in x = 28 to find y

The next part after that, you plug in y = 6.50 and solve for x

Answer 5

y=0.05(28)+3 will be 22 over 5, which then switches to 4.4 as a decimal.

Answer 6

yes, when x = 28, y = 4.4

So it costs $4.40 to print 28 pages

Answer 7

The next one 6.50=0.05(x)+3 would have 70 as the answer.

Answer 8

very good, if the total cost is $6.50, then you've printed 70 pages

Answer 9

or if your budget is $6.50, then you can only print 70 pages

Answer 10

Thanks soo much.
