Megan is checking her tax bill for the last year.

Tanya [424]

Given that Megan's tax rates were as follows:
No tax one the first £11000 of earnings
Earnings in excess of £11000 and up to £43000 taxed at a rate of 20%
Earning in excess of 43000 and up to £150000 taxed at a rate of 40%
Earnings over £150000 taxed at a rate of 45%
If Megan earned £158900 before tax last year, the amount of tax she paid in total is given as follows:
First £11000 = £0 tax
Balance after first £11000 = £158900 - £11000 = £147900

Next (£43000 - £11000 = £32000) = 20% of £32000 = 0.2 x £32000 = £6400 tax
Balance after next £32000 = £147900 - £32000 = £115000 

Next (£150000 - £43000 = £107000) = 40% of £107000 = 0.4 x £107000 = £42800 tax
Balance after next £107000 = £115000 - £107000 = £8000

Remaiming £8000 = 45% of £8000 = 0.45 x £8000 = £3600 tax

Total tax = £6400 + £42800 + £3600 = £52800

Therefore, she paid a total of £52800 in tax last year.

The number of letters in Stephanie's full name is sixteen less than twice the number of letters in Amy's full name. If the numbe

Anestetic [448]

Answer:

19 letters

Step-by-step explanation:

Suppose Number of Amy's full name letters = X

Number of Stephanie's full name letters = Y

Now, according to given condition that ''number of letters in Stephanie's full name is sixteen less than twice the number of letters in Amy's full name'',

Equation 1 becomes

Y = 2X-16

Now, according to second condition, product of their names' letter is 418. So,

Equation 2 becomes

XY = 418

Deducing value of X from equation 1,

X = (Y+16)/2

Putting this value in equation 2 we get,

{(Y+16)/2}*Y = 418,

By simplifying this equation we get a quadritic equation

(Y^2)+16Y-836=0

By breaking middle term (You can use quadratic formula here as well)

(Y^2)+38Y-22Y-836=0

Y(Y+38)-22(Y+38)=0

(Y-22)(Y+38)=0

At this stage we have two values for Y,

Y=22, or Y=-38

Now considering only positive value since the number of letters in a name can not be in negative number,

Y=22,

So X=(Y+16)/2

X=19
