What is the cost of strawberries in each strawberry shortcake if the strawberries have an as-purchased cost of $2.89 per pound and 3 ounces of them are used in each strawberry shortcake?

Answer 1

$2.89 per pound

16 ounces per pound

3 ounces = 3/16th of a pound

3/16 x 2.89

= about 54 cents for 3 ounces

= cost of one shortcake

At least in the US, where l lb= 16 ounces

but elsewhere with Troy Weight, 1 lb = 12 ounces

There 3 ounces would be 3/12 = 1/4 of a pound

and a shortcake of 3 ounces would cost 2.89/4

= about 72 cents.

1 Troy lb. = about 1.22 US pounds

So you get more for your $2.89 per Troy pound than for a US pound
