It currently costs $11.75 to get a general admissions ticket to see a movie at the movie theater. it cost $7.25 in 2010. estimate the percent increase to see a movie from 2010 to 2017.

Remark

That's quite a jump isn't it? The easiest way to do this is to find the fractional increase and change that to a percent.

Solution

7.25  * x = 11.75   Divide by 7.25

x = 11.75 / 7.25

x = 1.621

But the question says what is the % increase. That means you have to multiply 7.25 by something to get what 11.25

In all, you have to subtract 1 which gives 0.621

So % increase is 0.621 * 100% = 62.1%

Comment

We have to try this out.

7.25 * 62.1/100 = 4.50

7.25 + 4.50 = 11.75 just as it should.

answer: the answer is 30 miles per hour.

ft/s -> mphmph = ft/s 1.466667mph = 44 divided by 1.466667mph = 30.00000
