How much interest is earned in 2 years on an investment of $2000? The interest rate is 3%.

Mathematics

Lelechka [254]3 years ago

 In this sum we will calculate using the simple  interest.


Simple interest is calculated from the formula :

I  = PRT

where I is the interest, P is the principal, R is interest rate per year and t is time in years.

I = 2000 × 3 % x 2

We have to turn 3% to its decimal fraction which is 0.03, so:

I = 2000 × 0.03 × 2

I = 60 ×  2

I = 120

Therefore the interest earned in two years will amount to 120 $

100 POINTS solve the system using linear combination. show all work.{ 5x + 3y = 41 {3x - 6y = 9
PIT_PIT [208]

Answer:

y = 2

x = 7

Explanation:

  • 5x + 3y = 41
  • 3x - 6y = 9

<u>Make the coefficient of "y" in equation 1 same</u>

{ 5x + 3y = 41 } * 2     →  10x + 6y = 82  ........equation 1

                                  →  3x - 6y = 9 ........equation 2

<u>solving them using linear combination</u>

  • 10x + 6y = 82
  • 3x - 6y = 9

     ============

  • 13x = 91
  • x = 7

Find y:

  • 5x + 3y = 41
  • 5(7) + 3y = 41
  • 3y = 41 - 35
  • 3y = 6
  • y = 2
