solution

An automobile mechanic (M and a body shop (B) use each other’s services. For each $1.00 of business that M does, it uses $0.50 of its own services an 0.25 of B’s services, and for each $1.00 of business that B does it uses $0. 10 of its own sevices and $0.25 of M’s services. (15 pts.) a. Construct a consumption matrix for this economy. b. How much must M and B each produce to provide customers with $700o worth of mechanical work and $14,000 worth of body work?Use Gauss Jor dan Method to solve the problem. 6. The following table shows the lifting force on an aircraft wing measured in a wind tunnel at various wind velocities. Model the data (use linear regression) and estimate the lifting force at 2000 ft/s. (20 pts.) Velocity (100 1 ft/s) Lifting Force 0 (100 1bs) 3.12 15.86
