= price of a Widget, in $
= price of a Whatszit, in $
If the total sales were $463.96, we know that
--> dividing both sides of the equal sign by 5
Without much information, we cannot say more.
We could solve for as a function of and get

If the price has to be a whole number of cents (unlike the price per gallon for gasoline, which in the US seems to always end in 9/10 of a cent),
then the Widget must be priced at $ where is an integer such that .
The price of a widget could be $0.00. Maybe the vendor sells Whatszits at $16.57 each, and gives some Widgets for free with purchase of a Whatszit.
The price of a Widget could be $0.04, or $0.08, or ... or $13.20, or $13.24.
In between values would require prices for the Whatszits with fractional cents, as in a $10.3325 price for a Whatszit if the price for a Widget was $4.99.
