sales tax included.
Round your answer to the nearest cent, as necessary.

Answers

Answer:

Next I rounded it.

55.349325 = 55.35

Lastly, I added 819.99 plus 55.35

819.99 + 55.35 = 875.34

After a 40% discount, the cost of a sofa is $471.00. What was the original cost of the sofa? NEED HELP ASAP

Answers

Answer: $659.40

Step-by-step explanation: You start with 471.00 X 0.4 which equals $188.40. So then you add $471.00 and $188.40 and you get $659.40!

The percentage is calculated by dividing the required value by the total value and multiplying it by 100.

80% = $471

100% = $588.75

The original cost of the sofa is $588.75

What is a percentage?

The percentage is calculated by dividing the required value by the total value and multiplying it by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

We have,

Original cost in percentage = 100% ____(1)

Cost after 40% discount = $471

This can be written as,

80% = $471 _____(2)

From (1) and (2) we get,

80% = 471

Multiply 100/80 on both sides,

100/80 x 80% = 100/80 x 471

100% = $588.75

Thus,

80% = $471

100% = $588.75

The original cost of the sofa is $588.75

Answers

Answer:

3x+2y

Step-by-step explanation:

Find the rectangles attached

Area of a rectangle = Length * Width

A = A1+A2

given

A = 30cm²

A1 = 3 * x

A1 = 3x

A2 = 2*y

A2 = 2y

Substitute

30 = 3x+2y

Hence the required equation is 3x+2y = 30

Answer: 3x + 2y = 30

Step-by-step explanation:

A = L x W

The sum of the rectangle is 30.

One angle is 3 and x, the other one is 2 and y.

Multiply 3 with x = 3x.

Multiply 2 with y = 2y

Then create your equation plugging in 30 as the answer to 3x + 2y
