Find the 4 partial derivatives

The annual profit P (in dollars) of nursing homes in a region is given by the function P(w, r, s, t) = 0.007377w where w is the average hourly wage of nurses and aides (in dollars), r is the occupancy rate (as a percentage), s is the total square footage of the facility, and t is a number between 1 and 11 that measures the reimbursement rate in the region. A certain nursing home has nurses and aides with an average hourly wage of $15 an hour, a reimbursement rate index of 9, an occupancy rate of 80%, and 390,000 ft of space. b) Find the four partial derivatives of P.
