A car depreciates in value by 10% each year. If a car was bought for £4500, how much will the value of the car decrease by after 3 years?

 £1,219.5

Step-by-step explanation

Original price of car = £4500,

If the car depreciates by 10% after first year

New price = 90% of 4500

New price = 0.9 * 4500

New price = £4050

Second year

Price = 90% of 4050

Price = 0.9 * 4050

Price = £3,645

Third year:

Price = 90% * £3,645

Price = 0.9 * £3,645

Price = £3,280.5

Decrease in value = £4500 -  £3,280.5 = 1,219.5

Hence the  value of the car would have decrease by  £1,219.5 after 3 years

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
