Tim bought 5 shirts and 3 pairs of pants, and it cost him $250. scott bought 3 shirts and 2 pairs of pants, and it cost
him $160. all the shirts have the same cost, and all the pants have the same cost.
a. write a system of linear equations to find the cost of the shirts and pants.
b. show how this system can be written as a statement about a linear transformation of the form ll= b with
x =
and b =
160

c. determine whether l has an inverse. if it does, compute l−1b, and verify your answer to the system of
equations.
