Answer :
The number of miles in the taxi ride is approximately 22 miles.
The pick-up fee and the rate per mile are both constants, so we can represent them as [tex]$2.50 = c_1$[/tex] and [tex]$3.50 = c_2$[/tex], respectively. The total fare, including the pick-up fee and the charge per mile, can be represented as [tex]$79.50 = c_1 + c_2m$[/tex], where [tex]$m$[/tex] is the number of miles in the taxi ride. Solving for m gives us the equation:
[tex]$m = \frac{79.50 - c_1}{c_2}$[/tex]
Substituting the given values for [tex]$c_1$ and $c_2$[/tex] gives us the final equation:
[tex]$m = \frac{79.50 - 2.50}{3.50} = \frac{77}{3.50} = 22$[/tex]
Thus, the number of miles in the taxi ride is approximately 22 miles.
A constant is a value which does not change. It is a fixed value that is assigned to a variable and remains unchanged throughout the program. Constants are typically used to store values that are used repeatedly throughout the program, such as mathematical constants (e.g. pi, e, etc.) or physical constants (e.g. speed of light, Avogadro's number, etc.). Constants can be declared in a number of ways, such as defining a constant in the program code, initializing a constant when declaring a variable, or using a preprocessor directive.
