6 • 2(3x)
6 • 6x
3(2 • (2x))

, where,
I = Amount of interest,
P = Principal amount,
r = Annual interest rate in decimal form,
t = Time in years.
We are told that interest rates are 6% and 10%.


Amount of interest earned from lower-yielding account:
.
Amount of interest earned from higher-yielding account:
.

Amount invested in the lower-yielding account would be
.
Therefore, the man invested $60,000 at 6%.
