Angela is making cookies for the school bake sale. Her recipe calls for 2 cups of brown sugar. If the recipe she is using makes 8 dozen cookies, how much brown sugar will she need to make 10 dozen cookies? If x represents the amount of sugar needed to make the cookies, which of the following could not be used to solve the problem? graph table proportion equation

x = 2.5 cups

Cannot be solved by Graph.

Explanation:

According to the recipe:

Total cookies = 8 dozen

Total Sugar used = 2 cups

First we need to find the sugar required by 1 dozen of cookies. For that we have to divide the Total Sugar used by Total cookies:

Sugar required 1 dozen of cookies = 0.25 cups

Sugar required for 10 dozens of cookies = x = 0.25*10 = 2.5 cups

However, we cannot make a suitable graph for this because we need more data for that.
