Question

I paid twice as much by not waiting for a sale and not ordering on line. Which ofthe following statements is also true?

(a) I paid 200% more than I could have online and on sale.
(b) I paid 100% of what I could have online and on sale.
(c) I paid 200% of what I could have online and on sale.
(d) I paid 3 times what I could have online and on sale.

Answer 1

(c) I paid 200% of what I could have online and on sale.

Explanation:

The multiplier for a increase of a% is 1 + a/100.

In this question:

You paid twice, which means that the multiplier is 2. So

a is the increase, as a percent.

`1 + (a)/(100) = 2`

`(a)/(100) = 1`

`a = 100`

You had an increase of 100% on the price. Since the original amount was 100% you paid 100 + 100 = 200%(100% more, 2 times) of what you could have paid.

So the correct answer is:

(c) I paid 200% of what I could have online and on sale.
