What is the present value of a perpetuity that pays $90 per year if the appropriate interest rate is 9.3% ?? (Answer in $s to the nearest cent, i. e. xx. xx, with no $-sign or commas needed.)

How do i do this activity, is appreciated

Offering 30 if a plus b plus c equals 68 and ab plus bc plus ca equals 1121, where a, b, and c are all prime numbers, find the value of abc. the answer is 1978 but i need an explanation on how to get that.
