So you types 8x3 then you add. This is because you use PEMDAS on these type of problems

Both the given lines in graph intersect at point (5 , -2), the point must satisfy both the equations.
and if we check the options, we will observe that D. option has both the equations that satisfy the given conditions.
that is ~

put y = - 2,we will get :


so, 1st equation satifys the condition. let's check out 2nd one.

put y = -2



Hence, we can conclude that the Correct choice is D
Solution :
Given initial population = 300
Final population after 1 day = 800
Number of days = 6
∴ 
P(0) = 300 P(1) = 300
We need to find P(8).




When P(0) = 300

∴ c = 300
∴ 
When P(1) = 800


∴ k = 750

So, P(8) is

= 11,614
So the population becomes 11,614 after 8 days.
Round each number and then do what the problem asks you to do wether that be subtraction or addition.

if you need a different answer lmk and i’ll help :)
