Beverly moved into an apartment close to her new job. She will be paying $1800 per month in rent and expects a 3% rent increase each year. Express the rent y as an exponential function of the number of years rented, x.

y = 21600(1.03)^x

Step-by-step explanation:

The formula for determining exponential growth is expressed as

A = P(1 + r)^t

Where

A represents final value.

P represents initial value.

r represents rate of increase.

t represents number of years

She will be paying $1800 per month in rent. Since there are 12 months in a year, it means that the amount that she would pay in a year is

1800 × 12 = $21600. Therefore, P = 216000

She expects a 3% rent increase each year. This means that

r = 3/100 = 0.03

Therefore, the expression for the rent y as an exponential function of the number of years rented, x is

y = 21600(1 + 0.03)^x

y = 21600(1.03)^x

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.  

it is x equals 3   plese mark me really need it
