How to solve 3(n-3) = -10

-1/3

Step-by-step explanation:

Distribute-  3n-9=-10

Add 9 to both sides-   3n=-10

Divide both sides by 3-   n=-1/3

Check-   3(-1/3)-9=-10          (-1)-9=(-10)       -10=-10

Principal(P)= 12500

Rate(R)=8.5%

Time=3 years

Amount = Principal + Simple Intrest (S.I.)=?

Amount = P+S.I.

= 12500+3187.5

=15687.5

So, after 3 years he will receive 15687.5.
