The difference of two numbers is 18, and their sum is 90.
Find the two numbers

54 and 36

Step-by-step explanation:

when we add 54 and 36 we get 90 and when we subtract 54 from 36 we get the difference 18

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
