Answer: 50 cents
Step-by-step explanation:
Norman buys two cakes. One cake cost 40 cents and the other costs a quarter. Based on this, the cost of the second cake will be:
= 1/4 × 40
= 10 cent
Now, the total amount spent in total will be:
= 40 cents + 10 cents
= 50 cents
There are 10 possible digits and 26 possible letters.
To find the answer to this problem we have to multiply 9 as many digits has the hotel reservation number and 26 as many letters it has.
It means:

There are 1,119,214,746 possible reservation numbers.
