Contestants ABCDEFG and I are in a 10k race. In how many ways can C finish first and A finish second?

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

the answer is -1 1/5, also a

hope i

-lavira : )

i think the answer is a.( -3, -1 )
