Both the hot dog price and sales tax rate may contain decimal amounts, so they should be declared as type double constants. in visual basic, a constant is denoted by the keyword const. by convention, constant names are usually written in all upper case, with underscores to separate words. you also have to assign the value to a constant at the time you declare it (because, by definition, the value of a constant cannot be changed).

for example, the declaration of a constant double representing an delivery charge rate of 3.5% could look like this in visual basic:

const dbl_delivery_charge_rate as double = 0.035
