Which situation could best be represented by this linear equation? 2.75x + 3.25y = 215

The correct option 4.

Step-by-step explanation:

The given equation is

         .... (1)

Let x is the number of pretzels sold and y is the number of popcorn bags sold.

Total sales is defined as

        ... (2)

From (1) and (2) it is clear that,

The cost of each pretzel is $2.75 or 275 cents. The cost of each popcorn bag is $3.25 or 325 cents ($1 = 100 cents). Total sales is $215.

Pretzels cost is 50 cents less than popcorn bags. The variable x represents the number of pretzels sold and y represents the number of popcorn bags sold. The total sales was $215.

Therefore the correct option 4.
