I was wondering if someone can help me on my math questions? I am struggling

1. determine the interest rate on a loan of \$5400 if interest is compounded monthly for 72 months and finals of loan is \$6965.35.

list the values you used for present values, future values, number of years and numbers of compounding periods per year.

2. determine the monthly payment of a lease of \$21 568 if the interest rate is 4.8% compounded monthly for 48 months

3. over a five-year period, the maintenance on a car included two oil changes per year (\$48 each), new brakes (\$452), new tires(\$678) and a new set of spark plugs ($145). what is the average yearly maintenance fee on the car for the five-year period?

anything will be deeply appreciated
