Answer: Four Pints
When you go to the grocery store, drug store, or hardware store practice reading labels and comparing the different size boxes, cans and jars.
Compare apples to apples and Compare by unit price.
Two products with packages almost the same size, but not quite, must be compared by the price per unit. It is impossible to determine how many hundreds of dollars individual consumers waste each year because of their inability to use math skills to determine the best choices in everyday living.
A 10 ounce can of soup costs $1.50
An 18 ounce can of soup costs $2.50
Which has the lower cost per ounce?
Answer: $1.50 divided by 10 ounces = .15¢ per ounce
$2.50 divided by 18 ounces = .14¢ per ounce
The 10 ounce can instructs you to add a can of water to the concentrated soup contents. Now you have 20 ounces of soup. If a normal serving is 8 ounces, then one can will give you 2½ servings. (20÷8=2.5 servings)
The 18 ounce can of soup, says DO NOT ADD water. If a serving of soup is 8 ounces, then one can will give you 2¼ servings. (18÷8=2.25 servings)
Which is the better cost value?
The small, $1.50, can of soup yields 20 oz's.
$1.50 ÷ 20 ounces = 7½¢ an ounce
7.5¢ an ounce × 8 ounces = 60¢ a serving
The larger, $2.50, can of soup contains 18oz's.
$2.50 ÷ 18 ounces = 14¢ an ounce
14¢ an ounce × 8 ounces = $1.12 a serving
Answer: The smaller can of soup.
Which can has more servings?
Answer - the small can of soup.
