Answer: Miles earns 199.50$ in two days.

Step-by-step explanation: Since it says the hourly rate is 13.30$ and it says that he worked 7 hours on Friday you can write 7 x 13.30 = 93.1 After that now it says he worked 4 hours on Saturday and it says that on the weekends the hourly rate is doubled so you would write it as 4 (2 x 13.30) = 106.4 And so after all that add all the products so 93.1 + 106.4 = 199.50 $ that’s the answer it’s 199.50 $

{Answer:

3893 residents.

Step-by-step explanation:

Equation for population growth:

The equation for the size of a population, considering that it doubles every n years, is given by:

$A(t) = A(0)(3)^{(\frac{t}{n})}$

In which A(0) is the initial population.

The current population of a small town is 2463 people. It is believed that town's population is tripling every 12 years.

This means that $A(0) = 2463, n = 12$ . So

$A(t) = A(0)(3)^{(\frac{t}{n})}$

$A(t) = 2463(3)^{(\frac{t}{12})}$

Approximate the population of the town 5 years from now.

This is A(5). So

$A(t) = 2463(3)^{(\frac{t}{12})}$

$A(5) = 2463(3)^{(\frac{5}{12})} = 3892.8$

Rounding to the nearest whole number, 3893 residents.

The line seems to be starting at (3,0) and if you use the rule rise/run, it goes up (rises) 4 units and moves over (runs) 1 unit. You then rewrite this as 4/1 and you get 4 as the slope!
