I've moved your problem set from "Calculus" to an appropriate algebra category. Since you are (apparently) in calculus, you have already studied algebra, so you should have no difficulty in at least getting these started.

1. In 1989, Dutch ice skater Dries van Wijhe skated 200 km at an average speed of 35.27 km/h. How long was he skating?

Use the "d = rt" equation you learned back in algebra.

2. You deposit $1,000 in a certificate of deposit that pays 5.9% interest, compounded annually. What is your balance after 3 years.

3. You borrow $600.You pay 5% interest compounded annually. How much do you owe at the end of 4 years?

Use the compound-interest formula that you memorized back in algebra.

4. Use the function rule. Find y for x = 0, 1, 2, and 3.

y=x^2+1

Plug the given values into the specified variable in the given formula. Simplify to find the answers.

5. During a three-day premiere, a theater must sell an average of 200 tickets per night to make a profit. For the first two nights, 206 and 185 tickets were sold. How many tickets must be sold for the third night for the theater to make a profit?

How many tickets have been sold so far? (Hint: Add.) How many tickets do they need to sell, overall? (Hint: Multiply.) How many more tickets do they need to sell? (Hint: Subtract.)

6. A bank offers two interest account plans. Plan A gives you 6% interest compounded annually. Plan B gives you 13% annual simple interest. You plan to invest $2,000 for the next 4 years. Which account earns you the most interest (in dollars) after 4 years? How much will you have earned?

Apply the compound-interest formula to each scenario. Compare the results. What can you conclude?

If you get stuck on any of these, please reply showing all of your work and reasoning so far. Thank you!
