The federal government standard says that carbon monoxide (CO) levels should not exceed 35-ppm (parts per million) at any time. The concentration of carbon monoxide in the air in a certain metropolitan area can be modeled as ppm h hours after 7 A.M. Did the city exceed the 35-ppm maximum in the 8 hours between 7 A.M. and 3 P.M? If the answer is yes, give the time when the city first exceeded the 35-ppm maximum.
