Final answer:
To calculate the total cups of flour Amanda has, we multiply the number of containers (3 1/4 converted to 13/4) by the cups per container (2.3), giving us a precise answer of 7.475 cups, which is close to 7.25 cups.
Step-by-step explanation:
To find out the total cups of flour Amanda has, we need to multiply the number of containers by the amount of flour in each container. Amanda has 3 1/4 containers of flour, and each container holds 2.3 cups of flour.
Firstly, we convert the mixed number to an improper fraction:
3 1/4 = (3 × 4 + 1)/4 = 13/4
Now, we multiply the improper fraction by the number of cups per container:
(13/4) × 2.3 = 13 × (2.3/4)
13 × 2.3 = 29.9
29.9/4 = 7.475, which rounds up to 7.48 cups (if rounding to two decimal places).
However, we can see that none of the options perfectly match our calculated answer due to rounding, but the closest option to our calculation is Option D) 7.25 cups, which seems like a rounded down version of the precise answer.
