So basically, 9 cakes need 225 grams of flour
Therefore 1 cake needs: 

 = 25 grams of flour
Moreover, 20 cakes need: 20 × 25 = 500 grams of flour
500 g > 475 g
Marian does not have enough flour to make 20 cakes
 
        
        
        
Answer:
The answer is [10+(9x3]+4 and 5x4+(7x3).
Step-by-step explanation:
I can't really explain, but if you add 10+4, it'll be 14.
If you multiply 9x3, it'll be 27. 
So, if you add 27+14, it will be 41.
For the second answer:
If you also multiply 7x3, it'll be 21. If you ALSO multiply 5x4, its 20. So if you add 20+21, it will equal 41.
