Question

Skate station charges a flat rate of five dollars for skate rental plus 2 dollars per hour of skating . If the number of hours is represented by “h,” which algebraic expression represents the overall rate for “h”hours of skating

Answer 1

a flat rate simply means is a one-time-charge, so is really a constant, doesn't change with how many hours one skates for.

now, they charge 2 bucks per "h", so


`\bf \stackrel{\textit{cost}}{y}=\stackrel{\textit{2 bucks per hour}}{2h}+\stackrel{\textit{skate rental fee}}{5}`
