Answer 1

You posted this question earlier and I gave you considerable feedback on it.
I asked you to use letters to represent your unknowns. That's one of the first concepts you're exposed to in an Algebra course.

Let x=amount of money invested at 6% interest.
Let x-1900 = amount of money invested at 5% interest.

How much interest would x dollars produce in 1 year at 6% interest?

Note that interest = i = p r t, where i is the interest earned, p is the principal amount invested, r is the annual interest rate as a decimal fraction, and t is the number of years.

Amount of interest earned on x dollars at 6% interest over 1 year is ... what? Show all of your work (calculations).
