Answer:
Here, x represents the number of cans of sofa and y the number of boxes of popcorn,
Since, the cost of one can is $ 2,
⇒ The cost of x cans = 2x,
While, the cost of 1 box of popcorn is $ 1.5,
⇒ The cost of y boxes of popcorn = 1.5y,
Hence, the total spending = 2x + 1.5y,
Now, total spending can not exceed to $ 15
⇒ 2x + 1.5y ≤ 15 -----(1)
Which is the required inequality that shows the given situation,
Now, the related of this inequality is,
2x + 1.5y = 15,
That having x-intercept (7.5,0) and y-intercept (0,10),
Also, 0 + 0 ≤ 15 ⇒ 0 ≤ 15 ( true ),
The feasible region of inequality (1) will contain the origin,
And, ≤ sign represents the solid line.
Thus, by the above explanation, we can plot the graph of the given situation. ( shown below )
