Part A:
To get the interest of 1 year
Multiply 20,000 by 5% or 0.05
You get $1,000
Thats the amount for 1 year, now to get for 4 years, multiply 1,000, by 4
She pays $4,000 in interest
Part B:
If she pays it off in 2 years, instead of 4 years, she will pay an interest of $2,000, divide 4 by 2
Part C:
This is the same as part b, she saves $2,000
Hope this helps

Answer:
4
Step-by-step explanation:
(10 - x ) / x = 3/2 Cross Multiply
2*(10 - x) = 3x Remove the brackets
20 - 2x = 3x Add 2x to both sides
20 = 3x + 2x
5x = 20 Divide both sides by 5
x = 20/5
x = 4
Answer:
r = 1
Step-by-step explanation:
we know that :

Then

Then

Then
5×12 = 4×(16-r)
Then
60 = 64 - 4r
Then
4r = 64 - 60
Then
4r = 4
Then
r = 1
