A credit union loaned out $50,000, part at an annual rate of 6% and the rest at an annual rate of 12% . The collected combined interest was $3,600 that year. How much did the credit union loan out at each rate?

x = 6% amount      interest in one year  = .06 x

(50000-x) = 12% amount    interest after one year = .12(50 000 - x)       summed = 3600

 

 

.06x       +      .12(50 000 -x)         = 3600      solve for 'x'   the 6% amount, then 12% amount = 50 000 - x
