Catherine,

You need to find the price for (8 + 8 + 8 + 4) = 28 cans of cat food.

This works out to (3 x $4.50) + 4 x ($4.50/8) = (3 x $4.50) + ($4.50/2) = $13.50 + $2.25 = $15.75

Olney, MD

The $4.50 is for all 8 cans of cat food, so the cost for each can is:

$4.50/8 = $0.5625 per can [56.25 cents per can)

So for 28 cans:

($0.5625 per can)*(28 cans) =** $15.75**

-----

Another way to do it is to set up a proportion:

$4.50/8 = $x/28

Solve for x - same answer as above.
