Suppose the charge account of Strong's Mailing Service at the local supply store had a 1.8% interest rate per month on the average daily balance. Find the average daily balance if Strong's had an unpaid balance on March 1 of $126.40, a payment of $10 posted on March 10, and a purchase of $21.70 posted on March 20. The billing cycle ends on March 31.

What is the average daily balance?

Margaret Hillman invested $3,000 at 1.6% compounded quarterly for one year. Find the future value and the interest earned for the year. (Round to the nearest cent as needed.)

A loan of $4000 at 5% is compounded semiannually for 2 years. Find the future value and compound interest. Use the $1.00 future value table or the future value and compound interest formula.
