Profit from the sale of cars at a local car lot decreased rapidly between the years 2019 and 2023 according to the model $P'(t) = 2240e^{-0.03465t}$ where $t = 0$ represents the year 2019. If this trend continues in the future, estimate the total profit from the sale of cars from 2019. (Round your answer to the nearest dollar.)

Please use quick method to solve problems. 850N 850N 250 mm 250 mm 250 mm 250 mm 1200N Figure P5-13 R = R = 250N V = 850N M = 362.5Nm Special Instructions for this Homework: Just use the Quick Method (For Detailed Solutions of Quick Method see Sample Quizzes #11, #12). Figures P51 through P5-76 show a variety of beam types and bending conditions. For 20kN: 1. Compute the reactions at the supports. 2. Draw the complete shearing force and bending moment diagram. 3. Determine the magnitude and location of the maximum absolute value of the shear. 8.4 kN 2.5m 12.0 2.0 | 2.5m 12.5kN 15kN Figure P5-15 R = 37.4kN down R = 38.3kN up V = 24.9kN M = 50kNm
