Could someone kindly help me with this question?
The price P of an electronic component is known to be: P(c) = 2c - 18/c where c is the manufacturer's cost to produce it. The cost c is a function time t according to
c(t) = 9 + 3/t Determine the rate of change of price with respect to time (dP/dt) at time t = 3 years.
