If a bottle of soda costs $4.50, and the bottle costs $3 more than the soda, how much does the soda cost?

Answer:

$ 0.75

Step-by-step explanation:

A common mistake is to simply subtract $3 from $4.50, resulting in a cost of $1.50 for the soda. However, that's incorrect. To correctly set up this solution, create an equation, using "s" for the soda. You know that the bottle costs $3 more than the soda, so the bottle would be represented as s + 3, using the following steps:

s + (s + 3) = 4.50

2s + 3 = 4.50

2s = 1.50

s = 0.75

So the cost of the soda is $0.75. The bottle is $3 more than that, or $3.75.
