Question
Michael and Simon saved the same amount of money. Simon spent
Solution
Let's solve this step by step:
-
Let's denote the amount of money that Michael and Simon saved as "x".
-
After buying a birthday gift, Simon has "x - $120".
-
According to the problem, Michael has 4 times as much as Simon, so we can write the equation: "x = 4 * (x - $120)".
-
Solving this equation will give us the amount of money that Michael has.
-
If we distribute the 4 in the equation, we get "x = 4x - $480".
-
If we then subtract 4x from both sides of the equation, we get "-3x = -$480".
-
Finally, if we divide both sides of the equation by -3, we get "x = $160".
So, Michael has $160.
