Mrs. Jacobson wants to order toy instruments to give as prizes to her music students. The table shows the prices for various order sizes.
Whistles
25 items=$21.25
50 items=$36.00
80 items=$60.00
Kazoos
25 items=$10.0
50 items=$18.50
80 items=$27.20
a. What is the difference between the highest unit price for 6 whistles and the lowest unit price for whistles?
b. What is the highest unit price per kazoo?
c. If Mrs. Jacobson wants to buy the item with the lowest unit price, what item should she order and how many of that item should she order?
I am confused on this problem and really need some help on this one.
Thank you
