Barney spent $70 on 3 shirts and 2 pants and Robin bought 1 shirt and 4 pairs of pants for $90. (assume there is not sales tax). a) Write an equation to describe the total spent by Barney in the terms of numbers of shirts and pants purchased. Let x be the price of the shirt and let y be the price of a pair of pants.

b) Write an equation to describe the total spent by Robin in terms of numbers of shirts and pants purchased. Let x be the price of the shirt and let y be the price of a pair of pants.

c) Algebraically solve using either Substitution Method or the Elimination Method to solve the system of equations made up of your answer to part A and B. Show your work.

d) Use a graphing calculator such as Desmos to graph your equations in Parts A and B. What is the coordinate point where these two lines intersect? How does this compare to your response in part c?

e) What does the solution to the system of equations you got represent in the given scenario? Be specific.
