The floor manager of the factory earns €45,000 annually. She has a standard rate cut-off point of €28,000 and a tax credit of €4

lubasha [3.4K]

Answer:

She has to pay income tax of 8,570 Euros

Step-by-step explanation:

On the 28,000 Euros,the floor manager would pay taxes at the rate of 20% which is computed thus:

tax at 20%=28,000 Euros*20%=5,600 Euros

The remaining earnings would be charged to tax at higher tax rate of 41% as follows:

tax at 41%=45,000 Euros-28,000 Euros=17,000 Euros*41%=6,970 Euros

Total amount of taxes=5,600+6970 = 12,570 Euros

Taxes payable =total taxes -tax credit

The manager has a tax credit of 4,000 Euros

taxes payable= 12,570-4,000=8,570 Euros

The population of rabbits on an island is growing exponentially. In the year 1990, the population of rabbits was 1200, and by 19

kobusy [5.1K]

Answer:

2023 rabbits

Step-by-step explanation:

The exponential model consists of the following expression:

$y = A \cdot r^{t}$

Where:

$A$ - Initial population.

$r$ - Increase rate.

$t$ - Time

$y$ - Current population.

The initial population and increase rate are, respectively:

$1200 = A \cdot r^{0}$

$A = 1200$

$1700 = 1200 \cdot r^{4}$

$r^{4} = \frac{1700}{1200}$

$r^{4} = \frac{17}{12}$

$r = \sqrt[4]{\frac{17}{12} }$

$r \approx 1.091$

The exponential model that predicts the population of rabbits is:

$y = 1200\cdot 1.091^{t}$

Lastly, the expected population for the year 1996 is:

$y = 1200\cdot 1.091^{6}$

$y\approx 2023.624\,rabbits$
