Answer:
40% profit
Step by step Explanation:
Profit percentage
=( profit/cost price) * 100
0.2 = profit/cost
10+15+20+25+30= 100
Let's assume the cost price of the items is $1 each
Cost price total= $100
Profit made when buyer of 20 toffe didn't say was
0.2=profit/cost
0.2*100 =$20
If the$ 20 paid.
Total profit = $40
So percentage profit now
40/100 * 100 = 40%
The answer is: " 340 " . There are 340 nickels in 17 dollars.

Explanation:
______________________________________________
There are 20 nickels in one dollar.
Since 1 dollar = $1.00 = 100 cents ; and:
1 nickel = 5 cents
________________________________________________
(5 cents)*x = 100 cents ; solve for "x" ; x = the number of nickels in 1 dollar;
Divide each side of the equation by "5 cents" ;
[(5 cents)*x] / (5 cents) = (100 cents) / (5 cents) ;
to get:
_____________________________________________
x = 20 .
_____________________________________________
There are 20 nickels in one (1) dollar.
20 nickels * 17 dollars = number of nickels in 17 dollars.
___________________________________________________
20 * 17 = 340 nickels in 17 dollars.

The answer is: " 340 " . There are 340 nickels in 17 dollars.

Answer: 1.2
Step-by-step explanation:
First: Equations are solved. 
is an expression, and expressions can be simplified.
Now suppose 
. Imagine a right triangle with one angle (not the one opposite the hypotenuse, of course) labeled 
. This relation suggests that
and under the hood, we're assuming that 
, because otherwise we wouldn't be able to properly alternate from 
to so seamlessly.
Now,
so the given expression is the same as the tangent of that same angle .
If , then in the triangle, the leg opposite the angle occurs with the length of the hypotenuse in a ratio of to 2. By the Pythagorean theorem, the remaining side - call it 
- satisifies
and we have
