Answer:
The semiannual interest payment is $485.5
The total interest earned over the life of the bond is $10,681
Step-by-step explanation:
The formula of the simple interest is I = Prt, where
- P is the money invested
- r is the interest rate in decimal
- t is the time in years
∵ The bond is $20,000
∴ P = 20,000
∵ First Income Fund 11-year bond at 4.855%
∴ t = 11
∴ r = 4.855%
- Change it to decimal by divide it by 100
∴ r = 4.855 ÷ 100 = 0.04855
∵ The semiannual interest payment = P × r × half a year
∴ The semiannual interest payment = 20,000 × 0.04855 × (1)
∴ The semiannual interest payment = 485.5
The semiannual interest payment is $485.5
∵ I = Prt
- Substitute the values of P, r and t in the formula
∴ I = 20,000(0.04855)(11)
∴ I = 10,681
The total interest earned over the life of the bond is $10,681
Answer:
52
Step-by-step explanation:
We can write this out as an equation. Let's say that the teacher's age is x. Triple the teachers age plus the students age is 163, which can be written out as:
We want to isolate the variable, so subtract 7 from both sides. This gives us:
Finally, we divide both sides by 3, giving:
So the teacher is 52 years old.
