-19 + 4k - 15k - k -9

Let's simplify step-by-step.

−19+4k−15k−k−9

=−19+4k+−15k+−k+−9

Combine Like Terms:

=−19+4k+−15k+−k+−9

=(4k+−15k+−k)+(−19+−9)

=−12k+−28

=−12k−28

Step-by-step explanation:

soo this can be solve by using the formula:

f = p( 1 + i)^ n

where f is the future profit

p is the initial profit

i is the percent increase

n is the number of years

a . f = 30000 ( 1.05)^n

b. f = 30000 ( 1.05)^15

f = $62,368
