A person places $37700 in an investment account earning an annual rate of 5%,
lorasvet [3.4K]

Answer:

8,229,437 cents

Step-by-step explanation:

Using the compound interest formula;

A = P(1+r)^n

Given

Principal invested = $37700

rate r = 5% = 0.05

Time t = 16years

Substitute into the formula

A = 37700(1+0.05)^16

A  = 37700(1.05)^16

A = 37700(2.1829)

A = 82,294.37

Hence the amount of money, to the  nearest cent, in the account after 16 years is 8,229,437 cents

MatroZZZ [7]

Using a system of equations, it is found that Peter had $48 at first.

<h3>What is a system of equations?</h3>

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are:

  • Variable x: Peter's money.
  • Variable y: Henry's money.

The ratio of peters money to henrys money is 4 : 3, hence:

\frac{x}{y} = \frac{4}{3}

After Peter spent $12, they had the same amount, hence:

y = x - 12.

Then, replacing in the ratio:

\frac{x}{y} = \frac{4}{3}

\frac{x}{x - 12} = \frac{4}{3}

4(x - 12) = 3x

x = 48.

5. Walker is reading a book that is 792 pages. He reads
masya89 [10]
<h2>Forming Equations from Word Problems</h2>

To form equations from word problems, we can derive mathematical operations as well as variables from the given information.

In this case, each time Walker reads a certain number of pages, we subtract that from the total number of pages left to know how many pages is left to read.

<h2>Solving the Question</h2>

<em>Let r represent the pages left to read.</em>

<em />

792 pages in total

  • ⇒ <em>r</em> = 792

Walker reads 15 pages a day during the week and 25 pages a day during the weekend.

  • There are 5 weekdays, and he reads 15 pages each of those days. ⇒ <em>r</em> = 792 - 5×15
  • There are 2 weekend days, and he reads 25 pages each of those days.
    ⇒ <em>r</em> = 792 - (5×15 + 2×25)

5 weeks have passed

  • Multiply the terms representing the number of pages he reads a week by 5, for 5 weeks.
    ⇒ <em>r</em> = 792 - (5×15 + 2×25)×5

<h2>Answer</h2>

<em>r</em> = 792 - (5×15 + 2×25)×5
