A company wants to accumulate tsh 100000 to purchase replacement machinery 8years from know.to accomplish this equal semi-annually payments are made to a fund that earns 7%compounded semi-annually.find the amount of each payment

let the payment be P

P (1.035^16 - 1)/.035 = 100000

solve for P on your calculator
you should get around ($4770 , not the exact answer so you will still have to do the calculation yourself)

To find the amount of each semi-annual payment, we can use the formula for the future value of an annuity:

FV = P * [(1 + r)^n - 1] / r

Where:
FV = Future Value (desired amount of TSH 100,000)
P = Payment amount
r = Interest rate per compounding period (7% per compounding semi-annually)
n = Number of compounding periods (8 years, which is 16 semi-annual periods)

Now, let's plug in the values into the formula and solve for P:

100,000 = P * [(1 + 0.07/2)^(16) - 1] / (0.07/2)

First, let's simplify the equation a bit:

100,000 = P * (1.035^16 - 1) / 0.035

Now, we calculate the value inside the brackets:

1.035^16 ≈ 1.68043

So, the equation becomes:

100,000 = P * (1.68043 - 1) / 0.035

Now, let's simplify further:

100,000 = P * 0.68043 / 0.035

Next, we isolate P by multiplying both sides by 0.035:

3,500 = P * 0.68043

Finally, divide both sides by 0.68043 to solve for P:

P ≈ 5,138.20

Therefore, the amount of each semi-annual payment would be approximately TSH 5,138.20.
