We are told that 3 pints of raspberries cost $12. we are asked the following questions:
A. What is the cost per pint?
To determine the cost per pint we need to divide the cost over the number of pints, like this:
[tex]\frac{12dollars}{3\text{ pints}}=4\frac{dollars}{\text{ pint}}[/tex]That means that the cost per pint is $4.
B. How many pints do you get per dollar?
To determine the cost per dollars we need to divide the number of pints over the cost, like this:
[tex]\frac{3\text{ pints}}{12dollars}=\frac{1}{4}\text{ pint/dollar}[/tex]Therefore, you get 1/4 pint per dollar.
C. At this rate, how many pints can you afford for $20.00?
To determine how many pints you get for $20, we multiply the cost per dollars by 20, like this:
[tex]\frac{1}{4}\text{ pint/dollar}(20\text{dollars)}=5\text{ pints}[/tex]Therefore, you get 5 pints for 20 dollars.
D. At this rate, how much will 8 pints of raspberries cost?
To determine how much 8 pints cost, we multiply the cost per pint by 8, like this.
[tex]4\text{ dollars/pint (8pint)=32 dollars}[/tex]Therefore, 8 pints cost $32
