Answer:
40
Step-by-step explanation:
The amount of students who don't take either class is 8% * 200 = 0.08 * 200 = 16 which means that the sum of students who take the classes is 200 - 16 = 184. Let's call the amount of French students x. Therefore the amount of students who take History is 4x and the amount of students who take both is 10% * 4x = 0.4x. To find x we can write:
(x + 4x) - 0.4x = 184
4.6x = 184
x = 40 so the answer is 40.
