Question

a store is selling strawberries at $1.75 per pound. You would like to make 4 strawberry pies. Each pie uses 15 oz strawberries. How much will is cost to buy enough strawberries to make your 4 pies? Assume you can use the strawberry hulls in your pies. In other words, you don't need to account for waste. Recall that there are 16 ounces in 1 pound and 3600 seconds in 1 hour.

Answer 1

9514 1404 393

Answer:

  $6.56

Step-by-step explanation:

In the end, it's a units conversion problem. We want to convert units of pies to units of dollars. Along the way, we use conversion factors of (strawberry ounces per pie) and (dollars per strawberry ounce).

  $4\text{ pies}\times\dfrac{15\text{ oz}}{1\text{ pie}}\times\dfrac{\ 1.75}{16\text{ oz}}=\ \left(\dfrac{4\times15\times1.75}{1\times16}\right)=\ 6.5625$

The strawberries for 4 pies will cost about $6.56.
