Byron has money in his savings account. He spent $40 of it on a new winter coat. He has $80 left. How much money did he have in his savings account before he bought the winter coat?x = 40 dollars
x = 120 dollars
x = 2 dollars
x = 3200 dollars
Let's assign the unknown value as "x."
Since Byron spent $40 on a new winter coat and has $80 left, we can set up the equation:
x - 40 = 80
Adding 40 to both sides, we get:
x = 120
Therefore, Byron had $120 in his savings account before he bought the winter coat.
