Answer: A
Explanation:
First you have to write the model in an equation form. 
6x+5=15
Subtract 5 from both sides
6x=10
Divide 6 from both sides
X=10/6
Simplify
X=5/3 or 1.67
        
                    
             
        
        
        
Let's assume you have supplement angle 

Now when you talk about multiplication you can simply say...

And that will give you the answer.
 
        
        
        
Answer:
937.5 packs of apples
Step-by-step explanation:
Note that: 
100p = £1
80p = x
Cross Multiply
100x = 80p × £1
x = 80/100
x = £0.8
Jay sells 10 packs of apples for 80p. 
Hence:
£0.8 = 10 packs of apples
£75 = x
Cross Multiply
£0.8 × x = £75 × 10 Packs
x = £75 × 10 Packs/£0.8
x = 937.5
Therefore, to make £75 at the end of the year, he has to sell 937.5 packs of apples
