A
36
B
3.6
C
1.36
D
0.36
Correct answer: C
Explanation
Choice C is correct. It’s given that the number k is 36% greater than 50. Therefore, the value of k is the number 50 plus 36% of 50. This can be rewritten as . Multiplying the terms yields 18, so , or . It’s also given that k is the product of 50 and r, which can be rewritten as . Substituting 68 for k yields . Dividing both sides of this equation by 50 yields .
Choice A is incorrect. This is the percentage that k is greater than 50. Choice B is incorrect and may result from a calculation error. Choice D is incorrect. This would be the value of r if k were 36% of 50, instead of 36% greater than 50.
