All you have to do is take $630 and multiply it by 3.9% to get $24.57. Then take $1,047.69 and subtract the initial amount in the account ($630) to get $417.69 then divide that by the interest per month I assume ($24.57) to get 17. So I believe that the account has been held for 17 months. To check simply take $630 multiply it by 3.9% then multiply that by 17. I hope this helped if not please tell me where I went wrong.

Assuming he works at a constant rate, the daily rate Mark rakes lawns in the fall is 40% of the daily rate he mows lawns in the summer.

Fall:
5 neighbors' lawns / 2.5 hours = 2 lawns per hour
Summer:
6 neighbours' lawns / 1.2 hours = 5 lawns per hour
2 x 100% / 5 = 40%
2 is 40% of 5
