When an additional 2% is added to the subsequent year, you must multiply the earnings of the previous year with 1.2, because that means 100% plus and additional 2% of the base price. The solution is as follows:

First year: $30,000
Second year: $30,000(1.2) = $36,000
Third year: $36,000(1.2) = $43,200
Fourth year: $43,200(1.2) = $51,840

<em>In his fourth year, he made $51,840. His total earnings is the sum of all the individual earnings per year, which is equal to $161,040.</em>

18% of what number is 7.2?
RUDIKE [14]
18% of 40 is 7.2

Change the percentage (18%) into a decimal by dividing it over 100:

18/100 = 0.18

Divide 7.2 by the decimal (0.18):

7.2 / 0.18 = 40

The price of products may increase due to inflation and decrease due to depreciation. Derek is studying the change in the price
iren [92.7K]
Part A.

1) Function given:

f(x)=0.69(1.03)^x

2) Interpretation:

initial value: => x = 0 => f(x) = 0.69

table:

x                f(x)
year          price

0              0.69

1             0.69 * 1.03 = 0.7107 => increase = 3%

2             0.69 * (1.03)^2 = 0.732021 => increase = 3%

So, the answer is that the function is increasing at 3% per year.

Part B.

3) table

<span> t (number of years)      1             2              3                  4
f(t) (price in dollars)     10,100    10,201     10,303.01   10,406.04

Percent change:

Year 2: 10,201 / 10,100 = 1.01 => 1% increase

Year 3: 10,303.01 / 10,201 = 1.01 => 1% increase

Year 4: 10,406.04 / 10,303.01 = 1.01 => 1% increase.

Answer: the </span><span>product of the part A recorded a greater percentage change in price over the previous year (3% vs 1%).</span>

Will give brainliest for correct answer.
Naddika [18.5K]
The answer to this problem is all real numbers except for 4. When looking at this function, one can see that most numbers are possible. But, the only number that won't be possible is four. That's because the fraction \frac{1}{x-2} will always equal something greater than or less than zero. Since it's never going to equal zero, and since there is already a 4, that means that the range of this function is all real numbers except for 4.
