A. 2.10b+12.99=21.39; 4 bottles
B. 2.10+12.99b=21.39; 4 bottles
C. 2.10c= 21.39+12.99; 6 bottles
D. 21.39-2.10b=12.99;16
My answer is A am I correct?
yes. good job.
great job
……...? WHY?! and yes, A
To find the correct answer, let's set up an equation based on the given information.
Let b represent the number of bottles of water Raymond bought.
The cost of the bottles of water can be calculated as 2.10b, and the cost of the large pizza is $12.99. The total cost is $21.39.
Therefore, we can write the equation as:
2.10b + 12.99 = 21.39
Now, let's simplify the equation to find the value of b.
2.10b + 12.99 = 21.39
2.10b = 21.39 - 12.99
2.10b = 8.40
Divide both sides of the equation by 2.10 to solve for b:
b = 8.40 / 2.10
b = 4
So, Raymond bought 4 bottles of water.
Now, let's check which option matches our result.
Option A is 2.10b + 12.99 = 21.39; 4 bottles.
This option matches our result, so your answer of A is correct.
I'll take the dislikes as a compliment.
