Hello!

The answer is:


WatchCost=StartingBalance-EndingBalance\\\\WatchCost=515.50-496.11=19.39

The cost of the watch is $19.39.

Why?

To solve the problem, we can create a linear equation using the given information about the starting balance and the ending balance.

We know that the starting balance was $515.50, and then, after writing a check to buy the watch, the balance was $496.11, so, writing the function we have:


WatchCost=StartingBalance-EndingBalance\\\\WatchCost=515.50-496.11=19.39

Hence, we have that the cost of the watch is $19.39.

Have a nice day!
