Find the simple interest on a loan of 20,000 at the rate of 5% in 3 years

3,000

Step-by-step explanation:

Loan = 20,000

Simple Interest per year = 5% of 20,000

=>

=> 5 * 200

=> 1,000

Simple Interest for 3 years = 3 * 1000

=> 3,000

3000

Step-by-step explanation:

SI = P × R × T

Use simple interest formula.

20000 × 5% × 3

1000 × 3

= 3000

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
