The number of machine parts produced at a manufacturing plant is based on the number of parts made in a given day and the number of hours worked. Let P = 14x2 + 100 give the number of parts that are produced since the start of the shift and H = x be the number of hours that are to be worked that particular day. Create the equation that would give the number of parts produced per hour.
