Okay here we use the compound interest formula with the growth formula which is a the end amount equals p. Starting amount one plus r over 100 where r. Is the interest rate and t. Number of years. So here I want p. to become three p. So the money I deposit triples are I want to find over 100 And T. is 10 years. So divide by P. On both sides I get three equals one plus Are over a 100 power of 10. Don't just take power 1 10th of both sides like this. So it was a calculator three power 1/10 Gives me 1.11 612. And here of course these two just cancel out And we have one plus are over a 100 Now take one from both sides. 0.11612 Equals are over a 100 which means Are has to be 11.612 percent. And what they want here. Okay no mention the back he receives. So I will just say then 11.6 per year if you compound annually
