erma4kov [3.2K]

Answer:

I = $ 8.00

Equation:

I = Prt

then, solving our equation

I = 80 × 0.1 × 1 = 8

PIT_PIT [208]

Answer:

Step-by-step explanation:

If she was given a discount of 12% then the amount to be paid becomes I=P×R×T/100

I=400000×12×20/100

I=960000

Amount to be paid =I +P= 960000+400000=1360000

To liquidate this amount in 20 years therefore will be A÷20

1360000÷20

=68000 yearly
