Question 192111: I have a text question and usually I solve them by using the rule of three, but it does not work here, can you help me?
The score N on a test varies directly as the number of correct responses x. Fred answers 33 questions correctly and earns a score of 55. What would Fred's score have been if he had answered 48 questions correctly?
I know that x = 33
I always get 87.27272727... but that cannot be correct.

33/x=55
55x=33
x=33/55
x=.6
48/.6=80 ans.
