Carys is checking her tax bill for the last year.
The tax rates were as follows:
• No tax on the first £11000 of earnings
• Earnings in excess of £11 000 and up to £43 000 taxed at a rate of 20%
Earnings in excess of £43 000 and up to £150 000 taxed at a rate of 40%
• Earnings over £150 000 taxed at a rate of 45%
Last year, Carys earned £45 600 before tax.
How much tax did she pay in total?

Tax = £7,440

Step-by-step explanation:

Given: Carys earned £45,600 before tax.

1) No tax on the first £11,000 of earnings ⇒ tax = 0

2) Earnings in excess of £11 000 and up to £43 000 taxed at a rate of 20%

3) Earnings in excess of £43 000 and up to £150 000 taxed at a rate of 40%

So, Carys earning in between £43,000 and £150,000

So, £45,600 = £11,000 + £32,000 + £2,600

The tax should she pay = £11,000 * 0 + £32,000 * 20% + £2,600 * 40%

    = 11,000 * 0 + 32,000 * 0.2 + 2,600 * 0.4

    = 0 + 6,400 + 1,040 = £7,440

So, she should pay £7,440

the number 100 represents the number of trials in the experiment.

49/100 represents the experimental probability of the coin landing heads up.

step-by-step explanation:

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.
