Question

Im sorry but this came right out of the book and I swear I typed it exactly the way it is and yes I know it's vague that is why I'm stressing out!
Ques: 'In a regular Pad Thai dish ordered in Annapolis, Maryland will sell for $11.50. In Parker, Colorado, it sells for $7.25. How much more are you paying in Maryland than in Colorado? What percent is this difference? Round to the nearest percent.'

Ok.... so first one is super easy. 11.50-7.25 = $4.25
The next question is where I am just not too sure about.
Is it 7.25/11.50 = 0.6304347 = 63% (???)

Edit: Reworked.

An easy solution would be to first acknowledge that the question calls for the percent of the DIFFERENCE. Therefore, you'll set up the fraction below:

4.25 / 11.50 = x / 100

From here, you'll solve for x: (42,500 / 11.50)

x = 3695.65

Then, move the decimal point 2 points to the left, because this is a percentage

Your answer is 37%

Are you sure it isn't 4.25 / 7.25 = 0.586207 = 59%?

To make it clearer, suppose it cost $1 in Colorado, but $2 in Maryland.  That's $1 more.  And you are paying 100% more ( double).  So it's 1/1, not 1/2 which would be only 50% more.

answer # 1  okay 
answer # 2:  divide the 'difference' by the Colorado price (4.25 /7.25) =  59% more based on the Colorado price for the same dish in Maryland. 


Check by multiply the Colorado price (7.25) by 59% (more in Maryland) = 11.53  pretty close
