Answer: Everybody will need to pay 3.18 dollars. ($3.18)

Step-by-step explanation:

To find out equal amounts of money, you need to divide the total cost by how many people there are. The total cost, in this case, is 12.72, and the amount of people in this problem is 4 people. That means, if everybody were to pay the same amount, you would need to divide 12.72 by 4.

12.72/4=3.18

A new phone costs $230 and the sales tax rate is 7%. What is the total cost of the camera after tax?
rosijanka [135]

That's a question about percentage.

One way to represent percentage is using decimal number. In this way, 1 is equivalent to 100% and the other less percentages using numbers between 0 and 1.

Examples:

  • 90% is equivalent to 0,90.
  • 5% is equivalent to 0.05. It's not 0.5 because 0.5 is equivalent to 50%.
  • 13.17% is equivalent to 0.1317.
  • 245% is equivalent to 2.45.

If we want to know the percentage of a number, we should multiplacate the number by the porcentage in the decimal number form.

Examples:

  • 55.90% of 200 is equal to: 200 \times 0.5590 = 111.8
  • 360% of 88 is equal to: 88\times 3.6 = 316.8

In our problem, we have a phone with a increase of 7%. To solve that, it's important to perceive that $230 is equal to 100% and with a increase of 7%, we will pay 107%.

107% in the decimal number form is 1.07. With that information, we should multiplicate 1.07 by the original value and we will find the answer.

We know that 230\times 1.07 = 246.1, therefore, the total cost of the phone after tax is $246.1.

I hope I've helped. :D

Paisley has 8\tfrac{1}{4}8 4 1 ​ cups of yogurt to make smoothies. Each smoothie uses \tfrac{11}{16} 16 11 ​ cup of yogurt. How
Ivenika [448]

Given:

Total Yogurt = 8\dfrac{1}{4} cups

Yogurt required for each smoothie = \dfrac{11}{16} cup

To find:

The number of smoothies that Paisley can make with the yogurt.

Solution:

We know that,

\text{Number of smoothies}=\dfrac{\text{Total yogurt}}{\text{Yogurt required for each smoothie}}

Substituting the given values, we get

\text{Number of smoothies}=\dfrac{8\dfrac{1}{4}}{\dfrac{11}{16}}

\text{Number of smoothies}=8\dfrac{1}{4}\times \dfrac{16}{11}

\text{Number of smoothies}=\dfrac{32+1}{4}\times \dfrac{16}{11}

\text{Number of smoothies}=\dfrac{33}{4}\times \dfrac{16}{11}

\text{Number of smoothies}=3\times 4

\text{Number of smoothies}=12

Therefore, the number of smoothies is 12.

When you bring something up or move something down, you have to multiply the exponent by -1. So in this case, you are bringing up the exponent. Multiply 5 by -1 and your answer should be x^5/1.
