Answer: OPTION C.
Step-by-step explanation:
The missing options are:
In order to solve this exercise you need to remember the following:
1. The Distributive property states that:
2. The multiplication of signs:
In this case the exercise gives you the following equation:
Since you need to solve for the variable "x" in order to find its value, the first step you must apply in the in the procedure is to eliminate the parentheses applying the Distributive property.
Then, you must multiply everyting inside the parentheses by .
Therefore,based on the explanation, you know that the correct use of the Distributive property is:
We need to find what percentage represents the number of Hershey's Cookie Crème Candy Bars in each package, and then compare which one is better.
For package A.
It has 13 Hershey's Cookie Crème Candy Bars out of 25. To find which percentage is 13 out of 25 we do the following:
• Divide 100 by the total amount of candy 25, and multiply the result by 13:
we get the following percentage:
Package A has 52% of Hershey's Cookie Crème Candy Bars.
For package B.
It has 11 Hershey's Cookie Crème Candy Bars out of 20. we do the same as before to find the percentage, only that this time, instead of dividing by 25, we divide 100 by 20, and intead of multiplying by 12, we multiply by 11:
The result is:
Package B has 55% of Hershey's Cookie Crème Candy Bars.
Which package should Alladin buy? He should buy Package B because it has a greater percentage.
