Thank you.
Can you help me with this one:
Stan invested \$13,000, part at 17% and part at 2%. If the total interest at the end of the year is \$1,910, how much did he invest at 17%?

• math -

Let Y = amount invested at 17%.
Then 13,000 - Y = amount invested at 2%.

Y + (13,000 - Y)*0.02 = 1910.
Solve for Y.
