+191 Hi everyone, could someone help me to resolve this ?
The pollution level in the center of a city at 6am is 30 parts per million and it grows linearly by 25 parts per million every hour. If P(t) is the pollution level in part per million and t is the time elapsed after 6 am in hours, determine :
1. The function that relate P(t) with t ?
2. The pollution level at 4pm ?
Thank you so much !
