2.10b + 12.99 = 21.39

b = 4

Sorry -- leaving spaces around the decimal points is ugly.
Maybe you should have said math operator.

Let's use some clown math to solve this problem, shall we?

So, we know that Raymond bought bottles of water at $2.10 each. Let's say he bought b bottles of water. That means the cost of all the bottles of water would be 2.10b.

Next, he bought a large pizza for $12.99. So, the total cost of the pizza and the bottles of water would be 2.10b + 12.99.

We are told that the total cost was $21.39. So, we can set up the equation:

2.10b + 12.99 = 21.39

And there you have it! A clown-inspired equation to represent Raymond's water bottle purchase.

Let's say Raymond buys b bottles of water.

The cost of each bottle of water is $2.10.

So the total cost of b bottles of water is 2.10 * b.

The cost of the large pizza is $12.99.

Then the total cost of b bottles of water and a large pizza is 2.10 * b + 12.99.

According to the problem, the total cost is $21.39.

So the equation is: 2.10 * b + 12.99 = 21.39.

To answer this question, we need to set up an equation using the given information.

Let's assume that Raymond bought 'b' bottles of water. We know that each bottle of water costs $2.10. So, the cost of 'b' bottles of water can be calculated as 2.10b.

The total cost of the large pizza was $12.99.

So, the total cost of the purchase, including the bottles of water and the pizza, is $21.39.

To write an equation representing the given scenario, we add the cost of the bottles of water and the pizza:

2.10b + 12.99 = 21.39

This equation represents the relationship between the number of bottles of water bought and the total cost of the purchase.
