Question

María is using a double number line to determine the amount of flour she will need to make a batch of sugar cookies. If she wants to make a batch of 48 cookies, how much flour will she need?

a. 5 cups
b. 72 cups
c. 10 cups
d. 122 cups

Answer 1

María will need 8.0 cups of flour.

Step-by-step explanation:

Identify the relevant information:

The double number line relates the number of cookies to the cups of flour needed.

María wants to make 48 cookies.

Analyze the double number line (not provided in this case):

Look for a pattern or ratio between the number of cookies and the corresponding cups of flour.

For example, if 12 cookies require 2 cups of flour, then 24 cookies would require 4 cups of flour, and so on.

Calculate the flour needed for 48 cookies:

Based on the pattern identified above, determine how many times the original amount of cookies (12) fits into the desired amount (48).

In this case, 48 ÷ 12 = 4.

Since we are making four times the original number of cookies, we need four times the amount of flour.

Therefore, the total number of cups of flour needed = 2 cups/dozen * 4 dozens = 8.0 cups

Therefore, María will need 8.0 cups of flour.
