Question

PLZ FIRST ANSWER HELP ME 20 POINTS

Answer 1

300x10=3,000

-1,200=1,800

Explanation:

Answer 2

First of all, we need the actual, final cost. 20% of 1200 is

`(1200\cdot 20)/(100)=120\cdot 2=240`

So, if you add this extra to the initial cost, you have

`1200+240=1440`

Subtract the initial deposity of 300, and you'll get what remains to be paid.

Divide this remainder by 10 and you'll get the monthly payment.
