Final answer:
The original amount for which 1,440 is 120% is calculated by dividing 1,440 by 1.2, giving us the answer of 1,200. Therefore, option d is the correct answer.
Step-by-step explanation:
The question is asking to find the original amount for which 1,440 is 120%. This is a basic percentage problem where you want to find the base value (the original amount) if a given percentage of it equates to a known number (in this case, 1,440). To solve this problem, we set up a proportion:
120% = 1,440
Let x be the original amount:
120% of x = 1,440
To find x, we start by converting the percentage to a decimal by dividing by 100:
120 / 100 = 1.2
So the equation becomes:
1.2x = 1,440
Now, divide both sides by 1.2 to find x:
x = 1,440 / 1.2
x = 1,200
The original amount for which 1,440 is 120% is 1,200.
Therefore, the correct answer is d. 1,200
