How about
f(t) = 38 + 26t
where t is the number of hours spent in repairs.
f(t) = 38 + 26t
where t is the number of hours spent in repairs.
Let's say the time spent by the repair person is represented by the variable 't'.
The fixed cost of the house call is $38, which remains the same regardless of the time spent.
The variable cost is $26 per hour, meaning for every hour spent on the repair, the cost increases by $26.
To calculate the variable cost component, we multiply the time spent by the repair person, 't', by $26.
Therefore, the equation for the cost of a repair as a function of the time spent is:
Cost(t) = $38 + $26t
In this equation, 'Cost(t)' represents the total cost of the repair as a function of 't', the time spent by the repair person.
By plugging in different values for 't', you can find the cost of the repair for various time lengths.
