Question

Give a linear function for the cost see from the electrician to come to your house and wait for three hours he charges 95 flight for you to come to your house and 35 per hour he is there to work

Answer 1

SOLUTION TO QUESTION 1

Step1:Define the parameters

`\begin{gathered} \text{let cost be c} \\ \text{and } \\ \text{the time taken be t} \end{gathered}`

Step2: Write the given information

`\begin{gathered} \text{ \$95 for flight } \\ \text{and } \\ \text{ \$35 per hour of work } \end{gathered}`

Then, the total cost will be

`\text{ C=price for the flight+35}*\text{ number of hours he work}`

Step3: Write out the linear function in terms of t

`\begin{gathered} C(t)=95+35(t) \\ C(t)=95+35t \end{gathered}`

Therefore the linear function for the cost for the electrician to come and work will be

C(t)=95+35t
