Question

1. A certain store sells 2-liter bottles of pop for $1.19. They have a special on a 6-pack of 12 ounce cans for $1.50. (A 2-liter pop bottle contains approximately 67.2 ounces of beverage.)
a. Find the unit price

b. Which is a better buy


2.Maisie and Stitchie are two hungry kittens. You have exactly 3/4 cup of milk. If you divide the amount equally, how much will you receive?

3. Two rectangles are similar. The dimensions of the first are 2 feet × 8 feet. If the length of the second is 20 feet, what is its width?

Answer 1

1:  1.19 for 67.2 ounces is about 1.77 cents per ounce.  However, $1.50 for 72 ounces is about 2.08 cents per ounce.  Clearly, then, the first bottle is cheaper.

2.  We simply divide 3/4 by 2 to get (3/4)/2=3/(4*2)=3/8.

3.  If the length of the second is 20 feet compared to a 2-foot length for the first, the width of the second rectangle will be ten times the width of the first, so the width of the second rectangle is 10*8=80.
