Answer: 35

Step-by-step explanation: Well <em>percent</em> means <em>over 100</em> so we can set up an equation for this problem by reading it from left to right.

<em>What</em> means <em>x</em>, <em>is</em> means <em>equals</em>, <em>25%</em> is <em>25/100</em>,

<em>of</em> means <em>times</em>, and <em>250</em> means <em>250</em>.

So we have the equation x = 25/100 · 40.

Simplifying on the right side of the equation,

notice that 25/100 reduces to 1/4.

So we have x = 1/4 · 40.

Think of the 40 as 40/1.

So we can cross-cancel 140 and 4 to 35 and 1

and we have x = (1)(35) over (1)(1) or x = 35.

Now let's check our answer back in the

original problem to see if it makes sense.

We have (35) is 25% of 140.

Well we know that 100% of 140 would be 140.

So 25% of 250 should be a lot less than 140.

So 35 seems to make sense as a pretty good answer.

I have shown my work in the image attached.

Artemon [7]
For this case you can solve the problem by applying a simple rule of three in which we have
 520 ---> 100%
 800 ---> x

 Clearing x we have
 x = (800/520) * 100 = 154%
 the percentage increase in cost was
 154-100 = 54%
 answer
 the percentage increase in cost was 54%
