Answer: Both the situation are linear.
Step-by-step explanation:
Since we have given that
Cost of per hour = $14
Let the number of hour be 'h'.
So, our equation becomes
[tex]Amount=A(h)=14h[/tex]
Number of pounds he started bench pressing = 50 pounds
Number of lbs added every week = 5
Let the number of weeks be 'w'.
So, our equation becomes
[tex]Amount=50+5\times w\\\\A(w)=50+5w[/tex]
Hence, both the situation are linear.
