You buy 3 pounds of organic apples for $7.50. The graph shows the price for regular apples. What is the unit rate for each type of apple?
organic $2.50/pound; regular $3.00/pound
• organic $0.40/pound; regular $0.50/pound
• organic $2.50/pound; regular $2.00/pound
• none of the above
No, it’s option 3. The rise/run on the graph in the lesson is 2/1, which can be simplified into the whole number 2. So $2/lb for the regular apples.
From the given information, we know that you buy 3 pounds of organic apples for $7.50.
To find the unit rate, we divide the total price by the number of pounds.
For organic apples:
Unit rate = Total price / Number of pounds
Unit rate = $7.50 / 3 pounds
Unit rate = $2.50/pound
For regular apples:
From the graph, the price for regular apples is $3.00/pound.
Therefore, the unit rate for organic apples is $2.50/pound and the unit rate for regular apples is $3.00/pound.
So, none of the given options (• organic $2.50/pound; regular $3.00/pound) is correct.
To find the unit rate for each type of apple, we need to divide the cost by the weight of the apples.
For organic apples, we can divide $7.50 by 3 pounds: $7.50 ÷ 3 = $2.50/pound.
For regular apples, we can divide the cost by the weight, but the graph doesn't give us the exact cost for a specific weight. However, it does provide the price for one pound, which is $3.00. Therefore, the unit rate for regular apples would be $3.00/pound.
Therefore, the correct answer is: organic $2.50/pound; regular $3.00/pound.
