Find the rate of change of total revenue, cost, and profit with respect to time. Assume that R(x) and C(x) are in dollars. R(x) =55x - 0.5x , C(x) =3x + 20, when x =35 and dx / dt = 15 units per dayFind the rate of change of total revenue, east, and pmt wilh respect to time. Aesu me that Rm and Ch} are In dollars. dx R{x)=3x. C(x]=.1x2 +1.61: +5. 1when x=25 and E =3 units per day Suppose that the pride p. In deltare. and the numberef sates. it, of a certain item are reiated by 5p + 5x + 2p): = 35. it p and it are both functions of lime. measured in days. Find the rate at which it is d changing when it = 4. p = 5. and ED =13. The rate at which x is changing is |:] ':' {Round in the nearest hundredth as needed}
