Final answer:
Roger would pay approximately $20.13 for 1.75 pounds of rainbow cookies. This is calculated by converting ¾ to a decimal number and then multiplying the total weight of the cookies by the price per pound.
Step-by-step explanation:
To answer this question, we can multiply the weight of the cookies Roger plans to buy by the price per pound. The weight of the cookies is 1 ¾ pound and the price per pound is $11.50.
Firstly, we need to convert ¾ to a decimal number which is 0.75. So, Roger is buying 1.75 pounds of cookies.
Next, we will multiply the total weight of the cookies by the price per pound. So, 1.75 (total weight of the cookies) multiplied by 11.50 (price per pound) equals 20.125.
Therefore, Roger would pay approximately $20.13 for 1.75 pounds of rainbow cookies.
