<h3>How to add negative numbers along with positive?</h3>
We add all the negative numbers, all the positive numbers, then keep the signal of the higher absolute value, and subtract the values.
From the graph, we have that:
- The sum of the negative numbers is of 8.
- The sum of the positive numbers is of 2 + 4 = 6.
8 > 6, hence the profit is negative given by:
-(8 - 6) = -2 dollars.

Hourly wage = $12
Number of hours Peter worked = 20 hours
Gross Pay = Hourly Wage x Number of Hours worked
Using the values, we get:
Gross Pay = 12 x 20 = $240
Thus, the gross pay of Peter was $240 for his work of last week
Population are always modeled by exponential growth equation given by:
f(x)=a(1+b)^t
where:
a=original number
b=rate of growth
t=time
thus
f(x)=412(1.05)^t
the population after 9 months will be:
f(9)=412(1.05)^9=639.15=639
