Benson purchased a $1,800 certificate of deposit that earns simple annual interest. At the end of 1 year, the certificate was worth $1,857.60. What is the annual interest rate on this certificate of deposit?

3.2%

Step-by-step explanation:

Here, we want to calculate the annual interest rate

The interest is = Amount - principal = 1857.60 - 1800 = 57.60

‘Mathematically;

Interest = PRT/100

P is 1,800

r is rate

t is time = 1

57.60 = (1800 * r * 1)/100

100 * 57.60 = 1800r

r = 5760/1800

r = 3.2%

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5

10 - 75

step-by-step explanation:

there's nothing attached so it's most likely anything in that range.
