Luca is planning to pay the restaurant bill for his coworkers. The bill was $193.75. A 4% tax was then added by the waiter. If Luca wants to leave a 16% tip on the total amount including the tax, how much should Luca pay?

Answers

Answer:

If Luca wants to leave a 16% tip on the total amount including the tax, he should pay $32.24.

Step-by-step explanation:

First, you have to calculate the 4% of the bill and add that amount to the total of the bill to determine the total amount including the tax:

193.75¨*4%=7.75

193.75+7.75=201.5

Now, you have to calculate 16% of the amount including the tax:

201.5*16%=32.24

According to this, the answer is that if Luca wants to leave a 16% tip on the total amount including the tax, he should pay $32.24.

$201.50

Jordan can still spend at most $30 on her friends birthday gift.

Step-by-step explanation:

Total money need to spend at most = $45

Money spent on Yoga ball = $15

We need to find how much money she can still spend on her friend birthday gift.

the sum of the digits of a two-digit number is 11 the tens digit is one less thn three times the ones didgit find the original number

Answers

Answer:

The original number is 83

Step-by-step explanation:

let the number be ab

Sum of the two is 11

a + b = 11

tens digit a is one less than 3 times the ones digit

3b - a = 1

a = 3b - 1

3b -1 + b = 11

4b = 11 + 1

4b = 12

b = 12/4

b = 3

a = 3b - 1

a = 3(3) - 1

a = 9-1

a = 8

Mary deposits £10000 in an account which pays 5.6% compound
interest per year.
How much will Mary have in her account after 5 years?

Answers

Answer:

The amount Mary would have in her account in 5 years is approximately £13,131.7

Step-by-step explanation:

The amount Mary deposits in the account, P = £10,000

The amount in interest paid by the account, r = 5.6%

The mode by which the interest is calculated = Compound interest

The number of years for which the amount (£10,000) will be kept in the account, t = 5 years

The number of times that the given interest applies per year, n = 1

The amount, "A",  Mary would have in her account in 5 years, is given by the compound interest formula as follows;

[tex]A = P \cdot \left ( 1 + \dfrac{r}{n} \right ) ^{n \cdot t}[/tex]

Where;

A = The amount accrued in the account after the given elapsed periods

P = The principal or initial balance in the account = £10,000

r = The compound interest rate = 5.6/100

n = The number of times the interest is applied in one period of time = 1

t = The sum of the duration for the interest applies = 5

Substituting the given values, we have;

[tex]A = 10,000 \times \left ( 1 + \dfrac{0.056}{1} \right ) ^{1 \times 5} = 13,131.65883211776[/tex]

Therefore, the amount Mary would have in her account in 5 years = A ≈ £13,131.7

8. Flour = 150 grams

9. Original sum of money = 110 pounds

Step-by-step explanation:

8. Let the quantities of butter, flour and sugar be 2x, 3x and 4x grams respectively.

So,

2x + 3x + 4x = 450

9x = 450

x = 450/9

x = 50

Flour = 3x = 3*50 = 150 gram

9.

Let Abby, Neil and Dylan have 2x, 4x and 5x pounds respectively.

Since Neil has 40 pounds.

So, 4x = 40

x = 40/4

x = 10

Total amount = 2x + 4x + 5x = 11x = 11*10 = 110 pounds.

Original sum of money = 110 pounds

The carnival fundraiser at Westville Elementary School raised $300 on Friday. On Saturday, the carnival will raise 480 percent of that amount. Which statements are true about the amount of money that the carnival will raise on Saturday? Check all that apply. The answer will be less than $300 because 100 is less than 480. The answer will be greater than $300 because 480 is greater than 100. (100)(3) = 300, so 480(3) is the amount of money that the carnival will raise on Saturday. 480 + 300 is the amount of money that the carnival raised on Saturday. The carnival raised $780 on Saturday.
