Solve the problem.Tee-Tops Inc. has warehouses in San Francisco and Oakland and some stores in Berkeley and San Jose. The Berkeley store needs 4000 tee shirts and the San Jose store needs 7000 tee shirts. The Oakland warehouse has 9000 tee shirts, whereas the San Francisco warehouse has 8000 tee shirts. The cost of shipping a tee shirt from Oakland to Berkeley is $0.05, from Oakland to San Jose $0.15, from San Francisco to Berkeley $0.03, and from San Francisco to San Jose $0.12. The number of tee shirts that are shipped from each warehouse to each store is chosen in order to minimize shipping costs.(a) Define the variables.(b) Write the system of linear inequalities used in solving the problem.(c) Write an algebraic expression for the objective function.
What will be an ideal response?
| (a) | x = the number of tee shirts shipped from Oakland to Berkeley |
(b)
| (c) | shipping costs = 2x + 3y + 96,000 |

Obtain an equivalent system by performing the stated elementary operation on the system.Multiply the second equation by -1. x - 5y + z = 55x - 5y - z = -18 5x + y + 2z = -1 x - 3y + z = -22
A. x - 5y + z = 5 -5x + 5y + z = -18 5x + y + 2z = -1 x - 3y + z = -22 B. -x + 5y - z = -5 5x - 5y - z = -18 5x + y + 2z = -1 x - 3y + z = -22 C. x - 5y + z = 5 -5x - 5y - z = -18 5x + y + 2z = -1 x - 3y + z = -22 D. x - 5y + z = 5 -5x + 5y + z = 18 5x + y + 2z = -1 x - 3y + z = -22
