Using the chart "amount of $1 at compound interest" from previous reading section "more compound interest", find the total amount and amount of interest paid in the following compound interest problems. $900 at 6%, for 10 years

Step-by-step explanation:

We will use the formula,

A= P(1+r/n)^{nt}

where A= accrued interest

r= rate of interest (0.06)

t = time (10)

n = no. of times amount paid in a year

P = principle (900)

1) When calculated annually, we have n = 1 ,

A= 900(1+0.06)^{10}

 = $1611.76

Since A= Principle amount + interest

    Interest = 1611.76-900 = $711.76

2) When calculated semi annually, n = 2

A= 900(1+0.06/2)^{20}

  = 1625.5

Interest = $725.5

3) When calculated quarterly, n= 3

A= 900(1+0.06/3)^(30}

 = 1630.22

Interest = $730.22    

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9
