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
23 plus 7 is 30. Now you multiply that by 5 to get 150.
