Luisa's restaurant and Bill comes to $75.50, and she leaves a 15% tip. What is Luisa's total restaurant bill?

Answers

Answer 1

Answer:

The total amount is given by the equation A = $ 86.825

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the total amount in the restaurant be represented as A

Now , the equation will be

The amount of bill from the restaurant = $ 75.50

The percentage of tip by Luisa = 15 %

So , the amount of tip by Luisa = ( 15/100 ) x amount of bill from the restaurant

Substituting the values in the equation , we get

The amount of tip by Luisa = 0.15 x 75.50

The amount of tip by Luisa = $ 11.325

So , the total amount in the restaurant A = amount of bill from the restaurant + amount of tip by Luisa

Substituting the values in the equation , we get

The total amount in the restaurant A = $ 75.50 + $ 11.325

The total amount in the restaurant A = $ 86.825

Hence , the equation is A = $ 86.825

A quadrilateral ___________ has one pair of parallel sidesalways

Answers

A quadrilateral sometimes has one pair of parallel sides. Then the correct option is B.

What is a quadrilateral?

The quadrilateral has four sides and four angles. The sum of internal angles is 360 degrees.

If the quadrilateral has one pair of parallel sides is known as a trapezoid. And if the quadrilateral has two pairs of parallel sides is known as a parallelogram.

If all the angles are congruent then the parallelogram becomes a rectangle. And if all the sides are congruent then the parallelogram becomes a rhombus. If both sides and angles become congruent in the parallelogram then is known as a square.

A quadrilateral sometimes has one pair of parallel sides. Then the correct option is B.

Work the following pricing problems for services rendered. (For all calculations use hundredths.)Labor time = 4 1/2 hours
Overhead rate = 95%
Retail price of parts = $134.75
Total cost of job = $241.98
Hourly rate?

Answers

Answer:

Hourly Rate = $12.22 per hour

Step-by-step explanation:

$\text{Labor Time = }4\tfrac{1}{2}=4.5\thinspace{ hours}$

Overhead Rate = 95%

Retail price of parts = $134.75

Total cost of job = $241.98

Cost of labor = Total cost - Retail price

= 241.98 - 134.75

= $107.23

Now, labor works for 4.5 hours and ears a total amount of $107.23

$\implies\text{Amount earned in one hour or hourly rate = }(107.23)/(4.5)\n\n\implies \text{Hourly rate = }\$23.83\text{ per hour}$

Now, Labor will get 95% overhead rate

⇒ The labor is getting 100% already but an overhead of 95% is also given

$\text{So, Hourly Rate = }(23.83)/(1+0.95)\n\n\bf\implies\textbf{Hourly Rate = }\$12.22\textbf{ per hour}$
