Hi, can someone help me please.

-R_K is just born. It is expected that RK will start college at the age of 16 and will nish her imdergraduate studies after 3 years. Currently, college costs are $28,000 per year and are expected to rise at 5% per year till RK goes to college. RK's guardians are planning to save for RK's college expenses. The guardians may invest all college savings in a fund that returns 8% per year in order to pay for RK's cellege years. Determine how much the guardians must save
