The correct answer is A) 2.5x + 3.75 < 15; 4 sodas.
To find the maximum number of sodas you can buy, you need to determine the number of sodas (represented by x) that satisfies the given inequality.
The cost of sodas is $2.50 each, and you have $15. If you buy x sodas, the total cost for sodas is 2.5x dollars.
You also decide to get a bag of popcorn, which costs $3.75.
The total amount you can spend is $15.
Based on this information, the inequality that models the number of sodas you can buy while also getting a bag of popcorn is:
2.5x + 3.75 < 15
To find the maximum number of sodas, you need to substitute the values for x in the inequality until you find a value that makes the inequality true.
If you substitute x = 4, the inequality becomes:
2.5(4) + 3.75 < 15
10 + 3.75 < 15
13.75 < 15
Since 13.75 is less than 15, the inequality is true.
Therefore, you can buy a maximum of 4 sodas in this situation.
