ANSWER
EXPLANATION
The perimeter of the triangle is the distance around the triangle.
We need to apply our ability to convert word problems in to mathematical expressions.
we were told that the bottom of the triangle is units.
From the diagram perimeter
Four times the length of the bottom will be .
12 more than 4 times the bottom will be
Hence another side of the triangle is
Finally we were told that the last side is 3 more than the bottom, that will be
By performing a change of units, will see that the recipe only makes 21 cups of punch, so it is not enough for the whole class.
<h3>
Will the recipe make enough punch?</h3>
The class wants to make, <u><em>at least, 24 cups of punch.</em></u>
The recipe that they will use needs:
1 gal of ginger ale, 1 quart of orange juice, and 1 cup of lemon juice.
Let's write all of these quantities in cups, to see how many cups of punch this recipe makes:
- 1 gal = 16 cups.
- 1 quart = 4 cups
Then the recipe mixes:
16 cups of ginger ale, 4 cups of orange juice, and 1 cup of lemon juice, then this recipe makes:
16 cups + 4 cups + 1 cups = 21 cups
This is not enough for the 24 students.

The "mean" is the same thing as the "average".
To get the average, you add up all the numbers on the list,
then divide the big sum by the number of items on the list.
If there are 100 numbers on the list, then in order to find their average,
you would add up all 100 numbers, then divide the big sum by 100.
If you wound up with an average of 51.18, then you must have had
5,118 just before you divided it by 100. So the big sum is 5,118.
