Question

your bank balance is 515.50. if you write a check to buy a watch, your balance would be 496.11. how much dose the watch cost ? writ a linear equation on that models the situation

Answer 1

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!
