Answer: 1 : 1.48
Step-by-step explanation:
Adam was able to change £400 into 592 francs which means that the British pound is stronger because it was able to buy more Swiss francs. 
The exchange rate can be gotten using direct proportion:
400 : 592
1       : x
Cross multiply:
400x = 592
x = 592/400
x = 1.48
Exchange rate is:
= 1 : 1.48
 
        
             
        
        
        
B is the answer, 5,400 is the interest

Answer:
108
Step-by-step explanation:
Jesicca wants to make tarts
She uses 3/4 cup of flour per batch
Jessica has 9 cups of flour hence the number of batches she will make can be calculated as follows

= 12
= 12×9
= 108
Hence Jessica will make 108 batches of tart
