Let
a= melon
b= servings of melon
c= slice of melon
equation 1
a= 6b
equation 2
a= cb
equation 3
2/3a=a-1/3a
2/3 = 6b-1/3a
2/3cb= 6b-1/3cb
6b= cb
c= 6 slices
There are 6 slices per serving, thus Stephen ate 6 slices over the weekend
The answer is a because 8:15 am to 11:30 am is 3 hours and 15 minutes. 12:30 pm to 4:15 pm is 3 hours and 45 minutes. 45 mins + 15 mins = 60 mins which is an hour. 3 hrs + 3 hrs + 1 hr = 7 hrs

Answer: 30,240 different ways</h3>
====================================================
Explanation:
We have 8 people to start with. If we remove Alice and Bob, and replace them with Charlie (who will be a stand in for both people), then we have 8-2+1 = 7 people in this line. There are 7! = 7*6*5*4*3*2*1 = 5040 different permutations or line orderings for these seven people.
For any given permutation, replace Charlie with Alice and Bob. There are two ways to do this for any ordering. We could have Alice in front of Bob, or Bob in front of Alice. So there are 2 times as many permutations compared to 5040. In other words, there are 2*5040 = 10,080 different permutations where Alice and Bob are standing together.
This is out of 8! = 8*7*6*5*4*3*2*1 = 40,320 different permutations overall of arranging 8 people in a line.
This means there are 40,320 - 10,080 = 30,240 different ways to arrange 8 people such that Alice and Bob are not standing together.
In summary, the idea is to find out how many ways there are to have Alice and Bob together. Then we subtract that result from the total number of ways to arrange 8 people to get our final answer.
Answer:
you save 11 cents per apple if you buy them at the cheaper store
Step-by-step explanation:
to find the cost per apple we divide the price by the number of apples.
quick mart: 1.17/3=0.37 and shop and save: 2.40/5=0.48
as you can see the price is cheaper at quick mart. to see how much cheaper we subtract.
0.48-0.37=0.11
Our answer is 0.11 or 11 cents.
