To determine why Julianne's answer is incorrect, we need to calculate the cost of 0.92 of a pallet of flowers at $14.63 per pallet.

To find the cost, you would multiply:

0.92 × 14.63

Now let's do the multiplication explicitly:

  1. First, multiply 92 by 14.63 (ignoring the decimals for now): \( 92 \times 14.63 = 1345.56 \)

  2. Next, adjust for the decimal places. Since 0.92 has two decimal places and 14.63 also has two decimal places, the total number of decimal places in the product will be 4. So, we need to place the decimal 4 places from the right in 1345.56, which gives us:

    \( 0.134556 \)

Based on this correct multiplication, the error in Julianne's process could be the placement of the decimal point in her final answer.

Looking at the available options, the most relevant response would be:

  • The decimal in the answer is in the incorrect place.

This suggests that while she might have done the multiplication correctly, she likely made a mistake in positioning the decimal point in her final answer. So, the answer to the reason for which her answer is incorrect is that the decimal in the answer is in the incorrect place.
