Jameson is seeking a loan with a simple interest rate of 3% per year. If he wants to borrow $8000, then how much will he be char
Thepotemich [5.8K]

Answer:

$960

Step-by-step explanation:

You are going to want to use the simple interest formula for this. The one below is modified for solving the interest earned.

I=Prt

<em>I = interest amount </em>

<em>P = principal amount </em>

<em>r = interest rate (decimal form) </em>

<em>t = time </em>

The first step is to change 3% into a decimal:

3% -> \frac{3}{100} -> 0.03

Now, lets plug in the values into the equation:

I=8,000(0.03)(4)

I=960

Jameson will be charged $960 of interest after 4 years.

You have the following numbers: 1, 2, 3, 4, 5. Using these numbers, write at least 10 different mathematical expressions. Use at
masya89 [10]

Mathematical expressions allow us to relate numbers using mathematical symbols to make calculations. some examples are:

  • 2 + 3 = 5
  • 4 - 1 = 3
  • 2 × 2 = 4
  • 4 ÷ 2 = 2
  • 2² + 1 = 5
  • (1 + 2) + (2 × 1) = 5
  • (2 + 3) - 4 = 1
  • (2 + 2)² ÷ 4 = 4
  • (2 ÷ 4)² × 4 = 1
  • (2 + 2)² (4 ÷ 2) - (2 × 4)(5 - 1) + 5 = 5

<h3>What is a mathematical expression? </h3>

A mathematical expression is a sequence of characters that are intended to express a general relationship between the terms expressed in the formula.

Mathematical expressions generally have symbols like:

  • Add +
  • Subtraction -
  • Multiplication ×
  • Division ÷
  • Exponent x^{x}
  • Equal =
  • Parentheses ()

According to the above, some examples of mathematical expressions are:

  • 2 + 3 = 5
  • 4 - 1 = 3
  • 2 × 2 = 4
  • 4 ÷ 2 = 2
  • 2² + 1 = 5
  • (1 + 2) + (2 × 1) = 5
  • (2 + 3) - 4 = 1
  • (2 + 2)² ÷ 4 = 4
  • (2 ÷ 4)² × 4 = 1
  • (2 + 2)² (4 ÷ 2) - (2 × 4)(5 - 1) + 5 = 5
