I can solve with 2 methods:
I. Because the discount is 15 % of 18 $ , the price will be (100-15=85) 85 % of 18 $
18*85/100= 15,3 $ ( the sale price)
II. The discount is 15 % of 18$
15*18/100= 2,7$  ( the discount)
then I decrease it from the regularly price
18$-2,7$=15,3 $ (the sale price)
Personally I believe the first is an easier method.
I hope you understand and you can apply this in every similary problem.
        
             
        
        
        
Answer:
2.5
Step-by-step explanation:
From the diagram, figure B was enlarged to obtain figure A.
The two figures are therefore similar.
The corresponding sides are in the same proportion. That constant value of the proportion is called scale factor.
It is given by:

Figure B is the image of A

Therefore the scale factor is 2.5
 
        
             
        
        
        
<u>Half</u> of 4.50 is 2.25, so for <u>one</u> pound it would be <u>$2.25</u>.
To calculate five pounds, you need to add 2.25+2.25+2.25+2.25+2.25 = <u>11.25</u>.
For <u>five</u> pounds of strawberry's, it would cost <u>$11.25</u>.
Hope this helped !
 
        
                    
             
        
        
        
Answer:

Step-by-step explanation:
Given



<em>See attachment</em>
Required
Determine the area of K
First, we need to calculate the length of the rectangle  J

This gives:

Divide both sides by 22


So, the length of the rectangle J is 20.
Since both shapes are similar, then:

Substitute the known values:

Express as fraction:

Make Length, the subject of formula



The area of K is:
