The word problem only gives you two numbers, so it would be easy to assume that the questions involves those two numbers. However, in this case, the question requires that you calculate another answer first: the number of questions Abel got right. You'll need to subtract 4 from 80, then calculate the percentage of the difference:
80-4=78, and 78/80*100=97.5 percent So it will be 50

We are actually given here a right triangle where EC is
the hypotenuse. The length of one side is AE = 24, and the other side AC is
simply twice BC, so AC = 7:
EC^2 = AE^2 + AC^2
EC^2 = 24^2 + 7^2
EC = 25
340 you were right
