+CODING CHALLENGE 3
+
+
+
+
+John and his family went on a holiday and went to 3 different restaurants. 
+The bills were: $124, $48 and $268.
+
+To tip the waiter a fair amount, John created a simple tip calculator 
+(as a function). 
+
+He likes to tip: 
+20% of the bill when the bill is less than $50, 
+15% when the bill is between $50 and $200, 
+and 10% if the bill is more than $200.
+
+In the end, John would like to have 2 arrays:
+1) Containing all three tips (one for each bill)
+2) Containing all three final paid amounts (bill + tip).
+
+(NOTE: To calculate 20% of a value, simply multiply it with 20/100 = 0.2)
