3. The total cost C(in dollars) to rent a 14-foot by 20-foot canopy for d days is given
by the function C(d) = 150 + 30, where the setup fee is $30 and the charge per
day is $15. The setup fee increases by $20. The new total cost T' is given by the
function T(d) = C(d) + 20. Describe the transformation from the graph of C to
the graph of T.
