Answer: $50 + $2.49x = $67.43
Step-by-step explanation:
Let the case of water bought be represented by x.
We are informed that Sam's Club has a special that charges $2.49 per case of water and that Vinny wants to pay that price, but needs to purchase a membership first, which costs $50 and that Vinny eventually spent $67.43.
The equation that represents the number of cases of water that Vinny bought at Sam's club will be:
$50 + $2.49x = $67.43
