Utility, Substitution and Demand

### 5: Try it out (2) Change of Price

In the previous exercise, the optimum was 5 packets of crisps, 4 packets of nachos.

Now let's try the exercise again, but with the price of a packet of nachos changed from **62** to **67** pence. The other parts of the model are kept constant, including the five pound total budget and the price of crisps at **50** pence. Again, it is your turn to be a rational consumer and find the choice that maximises total utility.
