Final answer:
To find Michael's savings, divide the amount he spent ($210) by the percentage of his savings (30%) and solve the equation.
Step-by-step explanation:
To find out Michael's savings, we need to divide the amount he spent ($210) by the percentage of his savings that it represents (30%).
Let's set up the equation:
Savings * 30% = $210
We want to isolate the variable 'Savings'. To do that, we divide both sides of the equation by 30% (or 0.3).
Savings = $210 / 0.3 = $700
Therefore, Michael's savings is $700.
