) Ms. Pimentel went on a trip with the Glee Club. The trip was $365. Included in that price are $105 for a plane ticket, the cost of 2 luggage bags, and the hotel room for one night. The hotel room cost two times the amount of the plane ticket. What is the cost of one luggage bag? *

A. $25
B. $50
C. $130
D. $260

Answers

A. $25
The explanation would be because 365-105=206 and then double 105 which would be 210 and then subtract that from 206 which would be 50 then divide that by 2 and you would get 25
Let’s put that into an equation

Luggage bags will be represented in x
Since there’s 2 bags it will be 2x

The plane ticket cost $105. The hotel room cost TWO TIMES the amount of the plane ticket. So the hotel room would be 2(105)

Putting them together your equation would be:

365 = 105 + 2x + 2(105)

Now we solve from here:

2(105) = 210

210 + 105 = 315

Now we have:

365 = 315 + 2x

Isolate the variable so you have to Subtract 315 on both sides then you’ll have:

50 = 2x

Divide 2 on both sides:

25 = x

The cost of one luggage bag is $25.

What is Percentage?

Percentage is defined as the parts of a number per fraction of 100. We have to divide a number with it's whole and then multiply with 100 to calculate the percentage of any number.

Percentage is usually denoted by the symbol '%'.

Given that,

Selling price of the car = $37,000

Percent of commission earned = 8.5%

Amount of commission earned = 8.5% × $37,000

                                                    = (8.5 / 100) × $37,000

                                                    = 0.085 × $37,000

                                                    = $3145

Hence the commission earned is $3145.

You are a waiter at a restaurant. A family had a bill of $116.17. They leave you a 20% tip. How much of a tip did you get?

Answers

Answer:

Hello there! :) The tip they would leave you would be of $23.23

Step-by-step explanation:

The first step is to devide 116.17 by 100, which would equal 1.1617, which is obviously not your answer or a valid amount of money. But, you now take this 1.1617 by 20. Why? Becuase 20% is the same as 20 out of 100. Now you multiply 1.1617 × 20 and you will get $23.23.

Example on how to solve:


To figure out the tip, you need to find 20% of $52.60.
0.2×52.6=10.52
You should leave $10.52 for the waiter if you want to leave him exactly 20%.

To figure the tax, you need to find 8% of $52.60.
0.08×52.6=4.208
Next, add them up:
52.6+10.52+4.208=67.328
The total bill, including tax and tip, will be $67.33.
