Last Tuesday, the deli did not have any muffins. How did that affect the number of possible combinations?

A. It decreased the number of combinations by 1.
B. It decreased the number of combinations by 4.
C. It decreased the number of combinations by 8.

Answer :

To find out how the absence of muffins affected the number of possible combinations of the "commuter special," let's break down the options:

1. Determine the Original Options:
- Pastries: Donut, Brownie, Muffin, Scone, Croissant (Total: 5 options)
- Beverages: Coffee, Milk, Tea, Orange Juice (Total: 4 options)
- Papers: The Times, The Herald (Total: 2 options)

To find the total number of combinations available when all pastries (including muffins) are available, we would multiply the number of options in each category:

[tex]\[
\text{Total combinations with muffins} = 5 \times 4 \times 2 = 40
\][/tex]

2. Calculate Options Without Muffins:
- If the muffins are not available, the number of pastry options reduces to 4 (Donut, Brownie, Scone, Croissant).

Now, calculate the total number of combinations without the muffins:

[tex]\[
\text{Total combinations without muffins} = 4 \times 4 \times 2 = 32
\][/tex]

3. Determine the Decrease in Combinations:
- Subtract the total combinations without muffins from the total combinations with muffins to determine how many combinations were lost:

[tex]\[
\text{Decrease in combinations} = 40 - 32 = 8
\][/tex]

Thus, when the muffins were unavailable, the number of possible combinations decreased by 8.
