 // a) What is the target output when totalTill is called with the till object
+// a) The target output is £4.4
 
 // b) Why do we need to use Object.entries inside the for...of loop in this function?
+// b) Object.entries converts the object into key-value pairs,
+//    allowing us to access both the coin and its quantity.
 
 // c) What does coin * quantity evaluate to inside the for...of loop?
+// c) coinValue * quantity calculates the total value
+//    of that type of coin.
 
 // d) Write a test for this function to check it works and then fix the implementation of totalTill
