The sum of two numbers is 96, and one of them is 12 more than the other. What are the two numbers?	Options
A) 36 - 48 B) 50 - 34 C) 60 - 24 D) 42 - 54 E) 21 - 63

Rationale: "in this problem , we are asked to find two numbers . therefore , we must let x be one of them . let x , then , be the first number . we are told that the other number is 12 more , x + 12 . the problem states that their sum is 96 : word problem = 96 the line over x + 12 is a grouping symbol called a vinculum . it saves us writing parentheses . we have : 2 x = 96 â ˆ ’ 12 = 84 . x = 84 / 2 = 42 . this is the first number . therefore the other number is x + 12 = 42 + 12 = 54 . the sum of 42 + 54 is 96 . d"
Answer: D
