An arborist examined trees in an orchard to see if they were infected with a virus. The arborist counted 16 infected trees and 24 healthy trees. What percentage of the trees in the
orchard were infected?

I’m guessing that the answer is c, but i’m not sure which grid is being talked about. since 5x5= 25 and 3x3= 9 (which there are no answers for). a is not right because while the ratio is the same, 6/25= 0.24 which is equal to 24% not 30%.

32.10 is the correct answer
