The amount invested in the fund earning 8.5% is $40,000 whereas $20,000 was invested in the fund earning 10%
What is the return on each fund?
The return on each fund is determined as the amount invested multiplied by the interest rate on the fund
;Let X be the amount invested at 8.5%
Interest=8.5%*X=0.085X
The interest of the fund invested at 10%=($60,000-X)*10%
The interest of the fund invested at 10%=$6000-0.10X
Total interest=0.085X+6000-0.10X
Total interest earned during year 1=$5,400
5400=0.085X+6000-0.10X
5400=6000-0.015X
0.015X=6000-5400
0.015X=600
X=600/0.015
X=$40,000(amount invested at 8.5%)
amount invested at 10%=$60,000-$40,000
amount invested at 10%=$20,000

Answer:
put them in order
Step-by-step explanation:
1/2+2-3=309y6
Answer:
1. True
2. False
3. True
4. False
5. True
Step-by-step explanation:
1. For a real number a, a + 0 = a.
This is true, any number plus zero is that number.
2. For a real number a, a + (-a) = 1.
This is false. Adding a negative number is the same as subtracting that number. So a + (-a) = a - a = 0
3. For a real numbers a and b la-bl = |b-al.
This is true. Absolute value represents the distance between two numbers. This number can never be negative, therefore la-bl = |b-al.
4. For real numbers a, b, and c, a +(bº c) = (a + b)(a + c).
False. a + (b * c) = a + bc.
If you foil (a + b)(a + c) you will see its equal to a²+ab+ac+bc, which is definitely different than a + (b*c)
5. For rational numbers a and b when b# o, is always a rational number.
True, a rational number is one that can be written as a fraction with two integers. The quotient of two rational numbers can always be written as a fraction with integers.
