Mr. John invested in Fund A and Fund B. The total amount he invested, in both funds combined, was $100,000. In one year, Fund A paid 23% and Fund B paid 17%. The interest earned in Fund B was exactly $200 greater than the interest earned in Fund A. How much did Mr. John invest in Fund A?  Options:
A) $32,000	B) $36,000	C) $40,000	D) $41,000	E) $42,000
A+B=100,000   0.17B=0.23A+200   Take away decimals first: 17B=23A+20,000   Isolate first equation to solve for A (your goal): B=100,000-A   Plug in for B:   17(100,000-A)=23A+20,000   1,700,000-17A=23A+20,000   1,680,000=40A   1,680,000/40=A   A=42,000=Answer Choice $42,000
