Answer:
If the population grows by 4% each year then
the population in any given year is 104% of
the previous year or 1.04 times as much
P(t) = P0(1.04)t
P(t) is population at time t years
P0 = initial population = 11,000
t = number of years = 15
P(15) = 11,000(1.04)15
P(15) = 19,810 people
Step-by-step explanation:
First, create an equation with the criteria given.
If we let x be your number,

(

is twice the product of 3 and x, and if it exceeds

by 10, then we add 10 to

to make the two sides of the equation equal.)
Now, solve for

.

Answer:
<em>I earned $856 on the first day</em>
Step-by-step explanation:
Let's call
x = earning on the second day
2x = earnings on the first day
3x = earnings on the third day
The total earnings are $2568, thus
x + 2x + 3x = 2568
Simplifying:
6x = 2568
Dividing by 6:
x = 2568/6
x = 428
I earned $428 on the second day.
2x = 2*$428 = $856
I earned $856 on the first day
