Carpenter 4 U charges a consultation fee of dollar 50 Once
Solution
Consultation charges = $ 50
Per hour charge = $ 45
so let us take X is the total amount to complete the work and T indicate the number of hours.
so linear equation is X = $50 + T($45)
if the consultation fee is $60 instead of $50 then
linear equation is X = $60 + T($45)
