Question

As a fundraiser, a school club is selling posters. The printer charges a
$24 set-up fee, plus $0.50 for each poster. Then the cost y in dollars
to print x posters is given by the linear equation y=0.50x+24.

I have already answered parts A, B and C. Now I need help with part
D.

A) What is the cost y in dollars to print 50 posters? to print 100 posters?

The printing of 50 posters costs $49.

The printing of 100 posters costs $74.

B) Find the number of posters x if the printer billed the club for costs of
$84.00?

The number of posters, printed for $84.00,is 120.

C) Write the information from parts A) and B) as three ordered pairs.

The first pair from A) is (50,49).

The second pair from A) is (100,74).

The pair from B) is (120,84).

D) Use the data from part C) to graph the equation. Choose the
correct graph on the right.

I placed the 4 multiple choice graphs below.
