vthe waitress at the restaurant provided really good service so you and your friends decided to add on an 20% tip to your $32 bill. how much money will be added onto the bill for the tip?
The answer of the given question is $6.4, this is the money that need to be added onto the bill for the tip.
How to calculate a 20% tip?
To calculate tip, we need to multiply the total bill by 1 plus the decimal percentage tip we'd like to leave. If we wanted to leave a 20% tip, we would add 1 to 0.20 to get 1.20. Then, multiply the bill by 1.20 to get the total amount we'd leave including tip.
In this case, we have a $32 bill and we would like to add on an 20% tip. So, it will be as follows:
20% = 0.20
1 + 0.20 = 1.20
Total bill will be 1.20 x $32 = $38.4
Hence, the tip amount is $38.4 - $32 = $6.4

An oil company fills 1 over 12 of a tank in 1 over 3 hour. At this rate, which expression can be used to determine how long it will take for the tank to fill completely? (1 point)
a
1 over 12 • 3 hours
b
1 over 3 • 12 hours
c
1 over 3 • 1 over 12 hour
d
3 • 12 hours
Answer:
B. 1 over 3 x 12 hours
Step-by-step explanation:
The oil company fills 1/12 of a tank in 1/3 an hour. So, you multiply 1/3 times 12, since 12 is a full tank. It'll take 4 hours to fill the tank at this rate.
1/12 tank: 1/3 hour
2/12 tank: 2/3 hour
3/12 tank: Full hour
3/12 is equivalent to 1/4, meaning 1/4 of the tank is filled after 1 hour. Thus, it'll take 4 hours.

What is the smallest number of people (greater than $\color[rgb]{0.35,0.35,0.35}1$) who could have been at the party?
The smallest number of people when one could have been at the party is 211 people.
How to illustrate the information?This is a least common multiple question, also known as an LCM. We know this because all groups would have formed evenly if the one extra person had not arrived at the party. This means that there are 1 more people at the party than a number 2, 3, 5, or 7.
In this case, the number will be:
= (2 × 3 × 5 × 7) + 1

As per the concept of counting problem, the reason that the answers in part (a) and part (b) are not the same is because Q1 and Q2 are treated as two different coins in part (a) whereas they are effectively treated as the same coin in part (b). And the reason they are treated as one coin is because they both contribute the same amount to the sum of money.
Counting Problems
Basically, counting refers the process of finding the number of elements of a finite set of objects.
Given,
Suppose you have a nickel, two dimes, and a quarter. One of the dimes was minted in 1976, and the other one was minted in 1992.
While we looking into the given problem,
For A) states that, If you choose at least one coin, this means you could choose 1, 2, 3 or 4 coins. Let us label the dime as D, the penny as P, the quarter minted in 1976 as Q1 and the quarter minted in 1992 as Q2.
Here in this process if you choose one coin, you could choose either D, P, Q1, or Q2. This gives us 4 possible sets.
And If you choose two coins, you choose the following sets of coins: DP, DQ1, DQ2, PQ1, PQ2, Q1Q2. This gives us 6 possible sets.
Then If you choose three coins, you could the following sets of coins: DPQ1, DPQ2, DQ1Q2, PQ1Q2. This gives us 4 possible sets.
So, If you choose four coins, you can only choose DPQ1Q2. This gives us 1 possible set.
So, the total number of different sets of coins you can form is 4 + 6 + 4 + 1 = 15 different sets of coins can be formed.
Similarly, for b) If you choose at least one coin, this means you could choose 1, 2, 3 or 4 coins.
Then If you choose one coin you could choose either D, P, Q1, or Q2. However, since Q1 and Q2 give us the same sum, they are effectively the same set. This gives us 3 possible sums.
So, If you choose two coins, you could choose the following sets of coins : DP, DQ, PQ, Q1Q2.And this gives us 4 possible sums
Then If you choose three coins, you could choose the following sets of coins: DPQ, DQ1Q2, PQ1Q2. And this gives us 3 possible sums
Then If you choose four coins, you can only choose DPQ1Q2. This gives us 1 possible sum.
So, the total number of different sums of coins you can form is 3 + 4 + 3 + 1 = 11 different sums of money can be produced.
Finally, c) The reason that the answers in part (a) and part (b) are not the same is because Q1 and Q2 are treated as two different coins in part (a) whereas they are effectively treated as the same coin in part (b). And the reason they are treated as one coin is because they both contribute the same amount to the sum of money.
