Answer:
Part a) The variables are
x (the number of packages of Twinkies that were sold)
y (the number o boxes of juice that were sold)
Part b) The system of equations is
and
Part c) 
Part d) The value of y represent the number of boxes of juice that were sold 
The value of x represent the number of packages of Twinkies that were sold 
Step-by-step explanation:
Part a) Define the variables in this situation
Let
x-----> the number of packages of Twinkies that were sold
y----> the number of boxes of juice that were sold
Part b) Write a system of equations that model the problem
we know that
------> equation A
---> equation B
Part c) Use the linear combination method to find the solution to the system you wrote in part b
Multiply equation A by -1.65
------> equation C
Adds equation C and equation B

Find the value of x


Part d) Using a complete sentence, explain what the solution found in part c represents
The value of y represent the number of boxes of juice that were sold
so

The value of x represent the number of packages of Twinkies that were sold
so
