The final price (what it is selling for) is $796.40

The markup is 10% of the original price (the dealer's cost) , meaning that it is 10% more.

We need to find the original price.

We write this as an equation

The original price *110% = final price

This is because the original price is itself (100%) added with 10%

Plug in the known final price

Original Price * 110% = 796.40

Convert 110% to a decimal because the other numbers- such as the final price are also decimal numbers.

Convert 110% to a decimal by moving the decimal point up 2 spaces ( basically dividing it by 100)

110% = 1.1

So it is now

Original price *1.1 = 796.40

Divide both sides by 1.1 to isolate our unknown, the original price

Original price = $724

90/3 parts of silver = 30 times multiplied by
tin = 12 × 30 = 360g
lead = 8 × 30 = 240g

12.5 / 23 = 0.5434 parts per metal

tin = 12 × 0.5434 = 6.5kg
lead = 8 × 0.5434 = 4.5kg
silver = 3 × 0.5434 = 1.5kg

Consider Michelle and Gladys, two neighbors who each earn the same salary. Gladys pays less in federal income taxes than Michell
goldenfox [79]

Sad to say it is likely D.  If you are in the United States, I wouldn't know what deductions are available, but here are some possibilities.

1. Gladys is a single Mom. She gets to deduct her child.

2. Gladys owns her own home and gets to deduct her municipal tax. Michelle is renting and may be able to deduct something but not as much.

3. Gladys gets to deduct medical expenses. Michelle does not.

4. Gladys has a travelling allowance that is deductible. Michelle does not.

5. Gladys goes to church and tithes. Michelle does not.

6. Gladys has a registered savings plan. Michelle does not.

The problem is that the two women might very well be in a different tax bracket when all the deductions are considered. That depends on how the US system works. I don't think you are supposed to choose A. All other things being equal, they should be in the same tax bracket.

I don't see how B would come about. Usually state is dependent on Federal (it is in Canada anyway).

C is definitely wrong unless the savings plan is registered. Any savings plan that produces dividends or interest that is not registered is taxable.

What is the sum of 4 2/4 + 7 4/5 ?
lilavasa [31]
12.3 or 12 3/10

4.5 + 7.8 = 12.3

or

4 10/20 + 7 16/20 = 11 26/20

11 26/20 can be simplified to 12 6/20 and further simplified to 12 3/10

Suppose you received a job offer with a starting salary of $48,500 per year and a guaranteed raise of $1200 per year. Find the n
LuckyWell [14K]

Answer:

  • 7 years

Step-by-step explanation:

<u>This is going to be an arithmetic progression:</u>

  • 48500, 48500 + 1200, 48500 + 1200*2, ...

<u>So the first term is </u>

  • a₁ = 48500

<u>and the common difference is </u>

  • d = 1200

<u>Sum of AP is:</u>

  • S = (a₁ + aₙ)*n/2 = (2a₁ + (n - 1)d)*n/2

<u>Substitute and solve for n:</u>

  • (2*48500 + (n - 1)*1200)*n/2 = 321000
  • (97000 + 1200n - 1200)n = 642000
  • 1200n² + 95800n - 642000 = 0
  • 6n² + 479n - 3210 = 0

<u>Solving we get a positive root of:</u>

  • n ≈ 6.21 and it rounds up to 7 years
