ikadub [295]

Answer:

Lisa spends \frac{1}{6}\ hrs in reading and \frac{1}{6}\ hrs in watching television.

Step-by-step explanation:

Given:

Number of hours Lisa has = \frac{1}{3}

Now we need to find number of hours required to watch television and to read.

Given:

She splits her time equally between 2 activities.

Hence we can say;

Number of hours required to watch television and number of hours required to read both are half times equal to total number of hours.

Hence framing the equation we get;

Number of hours required to watch television = \frac{1}{2} \times \textrm{Total Number of hours she has}

Substituting the value we get;

Number of hours required to watch television = \frac{1}{2} \times \frac{1}{3} = \frac{1}{6}\ hrs

Number of hours required to read = \frac{1}{2} \times \textrm{Total Number of hours she has}

Substituting the values we get;

Number of hours required to read = \frac{1}{2} \times \frac{1}{3} = \frac{1}{6}\ hrs

Hence Lisa spends \frac{1}{6}\ hrs in reading and \frac{1}{6}\ hrs in watching television.

3.6% compounded quarterly=.036/4=0.009 per period
FV=5600(1+.009)^4y where FV=future value, and y is time, in years. So:
