Answer:

\displaystyle3\frac{3}{4}

Step-by-step explanation:

Hi there!

4\displaystyle\frac{11}{16} \div1\frac{1}{4}

Change mixed numbers to improper fractions:

= \displaystyle\frac{75}{16} \div\frac{5}{4}

Dividing by a fraction is the same as multiplying by its reciprocal:

= \displaystyle\frac{75}{16} *\frac{4}{5}

Reduce:

= \displaystyle\frac{75}{4} *\frac{1}{5}

= \displaystyle\frac{15}{4} *\frac{1}{1}

= \displaystyle\frac{15}{4}

Change improper fraction into mixed number:

= \displaystyle3\frac{3}{4}

I hope this helps!

Question 13
charle [14.2K]

The amount to be invested today so as to have $12,500 in 12 years is  $6,480.37.

The amount that would be in my account in 13 years is $44,707.37.

The amount I need to deposit now is $546.64.

<h3>How much should be invested today?</h3>

The amount to be invested today = future value / (1 + r)^nm

Where:

  • r = interest rate = 5.5 / 365 = 0.015%
  • m = number of compounding = 365
  • n = number of years  = 12

12500 / (1.00015)^(12 x 365) = $6,480.37

<h3>What is the future value of the account at the end of 13 years?</h3>

Future value = monthly deposits x annuity factor

Annuity factor = {[(1+r)^n] - 1} / r

Where:

  • r = interest rate = 5.3 / 12 = 0.44%
  • n = 13 x 12 = 156

200 x [{(1.0044^156) - 1} / 0.0044] = $44,707.37

<h3>What should be the monthly deposit?</h3>

Monthly deposit = future value / annuity factor

Annuity factor = {[(1+r)^n] - 1} / r

Where:

  • r = 6.7 / 12 = 0.56%
  • n = 2 x 12 = 24

$14,000 / [{(1.0056^24) - 1} / 0.0056] = $546.64
