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
= 600 (1.0511) = $630.66 = approx. $630

Answer:
Step-by-step explanation:
Lets Price of a DVD is fixed i.e. 15
and One CD price is 5 (Not fixed)
In First situation 
2 DVDs and 1 CD cost = 35 as given
2 x 15 + 5 = 35
Lets one CD price is 7.5
In Second situation
2 x 15 + 2 x 7.5 = 45
Its mean CD price may be between 5 to 7.5
In asked scenario, Martin has 50
1 DVD and 3 CDs?
1 x 15 + 3 x 7.5 = 37.5
37.5 is lesser than 50
Hence Martin has enough to buy 1 DVD and 3 CDs.
