Alladin went grocery shopping for candy at Costco in Rego Park. He wants to buy the package of candy with the greatest percentag
Pavlova-9 [17]

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:

\frac{100}{25}\times13

we get the following percentage:

\frac{100}{25}\times13=4\times13=52

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:

\frac{100}{20}\times11

The result is:

\frac{100}{20}\times11=5\times11=55

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.

The length of a rectangular fenced enclosure is 12 feet more than the width. If Farmer Dan has 100 feet of fencing, write an ine
Kitty [74]
Answer:
length = 31 ft
width = 19 ft

Explanation:
Assume that the width of the rectangle is w.
We are given that the length is 12 ft more than the width. This means that the length of the rectangle is w + 12

The perimeter of the rectangle in this case would be:
perimeter = 2 (length + width)
perimeter = 2 (12 + w + w)
perimeter = 24 + 4w

Assume that Dan would use all 100 ft of fencing to surround the yard. This would mean that the largest perimeter is 100 ft.

Therefore:
perimeter = 24 + 4w
100 = 24 + 4w
4w = 100 - 24
4w = 76
w = 19 ft

Since we have calculated that the width of the yard is 19 ft, we can substitute to get the length as follows:
length = 12 + w
length = 12 + 19
length = 31 ft

Hope this helps :)
