Julio says, "If you subtract 13 from my number and multiply the difference by -3, the result is -54 ." What is Julios's number?

Julios's number is 31

suppose: Julios's number is x

because Julio says, "If you subtract 13 from my number and multiply the difference by -3, the result is -54 "

=> we have: (x - 13).(-3) = -54

                 <=>  x  - 13 = (-54):(-3) = 18

                   <=> x = 18 + 13 = 31

                   <=> x = 31

Step-by-step explanation:

n = the annual frequency of compounding (how many times a year interest is added)

t = the number of years the money is invested
