Because your numbers are simple in this question, you can look at it this way...

You know how many cookies are needed for 15 students but you need to fiqure out how many for 30 students. The ratio between 15 to 30 is a 1:2, AKA double. THis means that you can simply double the known number of cookies and it will give you the amount that you need for double the people.
Your answer is 90 cookies.

<em><u>Problem One</u></em>

Remark

You don't pay a sales tax until cash is exchanged for goods or services.

So what is 70% off

Solution

Sale price = given price * (100% - 70%)

Sale Price = 72 * 30%

Sale Price = 72 * 30/100

Sale Price = 72 * 0.3

Sale Price = 21.6 dollars.

The sales tax is 5% of this amount

21.6 * 5/100 = 1.08

The total cost is = 21.6 + 1.08 = 22.68

Problem Two

If they marked up 100%, effectively they doubled the price.

New Price = old price + 100% of old price.

New Price = 48.50 + 48.50 = 97 dollars.

The sales tax is 6% * 97 = 6/100 * 97 = 5.82

Total Cost = Cost of item + Tax

Total Cost =97 + 5.82

Total Cost = 102.82 Answer <<<<

First of all you have to use the formula

a^2+B^2=c^2
a=6   b=4   c=?

6^2+4^2=?
36+16=?
after you add 36 and 16 find the square root
the square root of 52 is 7.211
if you don't want it in decimals you can just put it like this <span>sqrt(52)</span>
