Question 1

Given the total-revenue function
R(x) = 2x, 
and the total-cost function
C(x) = 0.01x² + 0.8x + 50,
if P(x) is the total profit function, find ΔP and P'(x) when x = 50 and Δx = 1.
◦ ΔP = $0.21; P'(50) = $0.20
◦ ΔP = $1.81; P'(50) = $1.80
◦ ΔP = $0.19; P'(50) = $0.20
◦ ΔP = $0.20; P'(50) = $0.19

Question 2

Given the total-revenue function
R(x) = 5x,
and the total-cost function
C(x) = 0.01x² + 2.2x + 80,
if P(x) is the total profit function, find ΔP and P'(x) when x = 100 and Δx = 1.
◦ ΔP = $0.79; P'(100) = $0.80
◦ ΔP = $4.19; P'(100) = $4.20
◦ ΔP = $5.19; P'(100) = $5.20
◦ ΔP = $1.79; P'(100) = $1.80
