Beanie Campbell just had a baby. He would like to be able to pay

for his child's college tuition starting 18 years from today. He

expects college to cost $50,000 per year (paid at the end of the

school year) for each of the four years his child is in school.

Beanie can invest/save at 5% per year.

How much money will Beanie need to have in 18 years?

How much will he have to save each year to afford college?

How would your answers change if the interest rate were

10%?
