Question

Your bank balance is $515.50. If you write a check to buy a watch, your balance would be $496.11. How much does the watch cost? Write a linear equation that models the problem.

Answer 1

Answer:

The watch costs 19.39

The equation is

515.50-w = 496.11

Step-by-step explanation:

Let the cost of the watch be w

Balance - w = new balance

515.50-w = 496.11

Subtract 515.50 from each side

515.50-515.5-w = 496.11-515.5

-w = -19.39

Multiply each side by -1

w = 19.39
