If you want explanation let me know!
I didn't provide one since you said ''What is the result''
1. Balance after 1 year with simple interest= 600 + (2.5 x 12) = 600 + 30 = $630
2. Balance after 1 year with compounded interest = P ( 1 + 

= 600 ( 1 + 
= 600 (1.0511) = $630.66 = approx. $630
$67.82 if you pay it on time.
$90.43 if you pay it late.
You will get the same answers but with more zeros. For example 7x20 is 140, and 7x2000 is 14,000 but with more zero's
