r-ruslan [8.4K]

Answer:

the interest owed is 1684.8

Step-by-step explanation:

Formula for simple interest =

I = Prt, where P is amount borrowed, r for interest rate and t for time.

Since the first three years is 1.6% interest we can write:

I = 15600 x 0.016 x 3

= 748.8

Then for the following 3 years the interest rate is 2%:

I = 15600 x 0.02 x 3

= 936

Adding the values gives us 1684.8

40%

<h3>Step-by-step explanation:</h3>

"Percent" means "per hundred". The "%" symbol is a shorthand way to write "/100" (divided by 100).

The fraction 20/50 is ...

... 20/50 = (20·2)/(50·2) = 40/100 = 40%

The number you want is 40.
