How do you do simple interest in math

simple interest:

principal x ( 1 + (rate as decimal x number of years))

 example if you put 100 dollars in a bank for 5 years at 5% interest at the end of the 5 years you would have:

100 x (1+(0.05 x 5)) = 100 x (1+(0.25)) = 100 x 1.25 = 125 dollars

125-100 = 25 dollars interest

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
