Question

I dont get this one, Helen Weller invested $14,000 in an account that pays 10% simple interest. How much additional money must be invested in an account that pays 13% simple interest so that the total interest is equal to the interest on the two investments at the rate of 11%?

Answer 1

14(10)+x(13)=(14+x)11
140+13x=154+11x
2x=14
x=7

Invest $7000 in the thirteen percent investment.

Answer 2

Thank you!!!!!!!
