Lonnie ordered 12$ copies of the same book. h3 books cost 19$ each and the order has a 15$ charge. what is the total cost of lonnie's order?

hello i might . what do you need.

friend me

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
