Formula to calc staff expenses

[bobbilockie]

I am very new to excel. I have created an expense sheet for the staff. It is to calculate for meals. Breakfast is 9.95, lunch 10.50, dinner 27.50. I would like a formula that the employee can simply enter the amount of meals (eg. 4 breakfast) and that cell will automatically multiply the 4 by 9.95 and display the total amount being $39.80. Breakfast lunch and dinner have their own cells so I would like to use the formula for each and then have a cell at the end with the total amount. Any help would be greatly appreciated.
