Stan invested $5,000, part at 8% and part at 17%. If the total interest at the end of the year is $490, how much did he invest at 8%?

For Further Reading

* math - Damon, Saturday, December 8, 2007 at 7:18pm

.08 x + .17 (5,000 -x) = 490

assuming simple interest not compounded monthly or daily or anything.

If x was invested at 8%, 5000-x was invested at 17%.

Solve the equation

490 = 0.08x + 0.17 (5000 -x)

490 - 850 = -0.09 x

0.09x = 360

x = ?

It says that the total interest earned in two accounts, was $490.
