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

1 answer:

6 0

Answer:
A = $ 2,120.00

Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 3%/100 = 0.03 per year,
then, solving our equation

A = 2000(1 + (0.03 × 2)) = 2120
A = $ 2,120.00

The total amount accrued, principal plus interest,
from simple interest on a principal of $ 2,000.00
at a rate of 3% per year
for 2 years is $ 2,120.00.

$\large\boxed{x=2,\ -2}$

Step-by-step explanation:

$\text{If the trapezoid EFGH is isosceles, then the angles}\ HEF\ \text{and}\ GFE\\\\\text{are congruent. Therefore}\ m\angle HEF=m\angle GFE.\\\\\text{We have the equation}\\\\4x^2+16=5x^2+12\qquad\text{subtract 16 from both sides}\\\\4x^2=5x^2-4\qquad\text{subtract}\ 5x^2\ \text{from both sides}\\\\-x^2=-4\qquad\text{change the signs}\\\\x^2=4\to x=\pm\sqrt4\\\\x=-2\ or\ x=2$

One number is 5 times a first number. A third number is 100 more than the first number. If the sum of the three numbers is 779,

Harrizon [31]

Answer:

97, 485, 197

Step-by-step explanation:

Given:

First number = a
Second number = b
Third number = c

Then we have:

b = 5a
c = 100+a
a + b + c = 779

Substituting b and c in the third equation:

a + 5a + 100+a = 779
100 + 7a = 779
7a = 779- 100
7a=679
a= 679/7
a = 97
b= 5*97 = 485
c = 100+ 97 = 197

The Science Club wants to print stickers to promote their club and an interest in science. They got a quote to print the sticker

zloy xaker [14]

Answer:

The system of equations =

25 + 0.05x = 12 + 0.09x

The number of stickers where the cost of both printers to be equal is 325 stickers

Step-by-step explanation:

Let the number of stickers = x

Printer 1

Pop Art Printing would charge a $25 setup fee and $0.05 per sticker.

$25 + $0.05× x

25 + 0.05x

Printer 2

Sticky Slogans would charge a $12 setup fee and $0.09 per sticker.

$12 + $0.09 × x

12 + 0.09x

We equate both equations together

The system of equations =

25 + 0.05x = 12 + 0.09x

Collect like terms

25 - 12 = 0.09x - 0.05x

13 = 0.04x

x = 13/0.04

x = 325 stickers

Therefore, the number of stickers where the cost of both printers to be equal is 325 stickers
