Shipping cost of something is defined like that: when the value is x<=100, cost is $3; when 100<x<=500, cost is D=(200+x)/100; when x>500, cost is$7. Now, someone shipped 2 batches of goods. Is the total value greater than 499?

1) One of the costs is $3 2) The total cost is$10

B it is.

stmt 1 is insuff since we don't know the shipping cost of the second object.
stmt 2 is Suff. Since total cost is $10. If one othe cost is$3 then the other one is $7 that means its >500. Lets say if its$4 +\$6, still using the given formula the prices have to be over 499.
