please solve question 1,2,3.

1. What is the present value of $100 ten years from now at a 5% discount rate? 2. How much money will be in your bank account three years from now if you invest $1,000 and receive 0.1% interest per month? 3. Your parents are nice enough to invest $1000 a year for the next two years in your child's college savings account starting on their first birthday. If you receive 4% interest, how much will this be worth when your child turns 18 (the first payment has 17 years to accumulate interest)
