2w=l-3

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%?

Let Y = amount invested at 17%.

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

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

Solve for Y.

Your questions are likely to be ignored if you post follow questions to an earlier one. It is better to post a different question under Post a New Question rathan than to piggy back on one to which a response has been given.
