Mary initially had R363 in her savings account.
Solución
Let's denote the initial amount of money Mary had in her savings account as \( x \) rand.
According to the information provided:
1. Mary draws R124 from her savings account to buy a new CD.
2. After drawing R124, she still has R239 in her savings account.
We can set up an equation based on the information:
\[ x - 124 = 239 \]
Now, we can solve for \( x \) to find out how much money Mary had to start with.
Solve the equation by following steps:
- step0: Solve for \(x\):
\(x-124=239\)
- step1: Move the constant to the right side:
\(x=239+124\)
- step2: Add the numbers:
\(x=363\)
Mary had R363 in her savings account initially.

To find out how much Mary had to start with, you can simply add the amount she withdrew (R124) to the amount she has left (R239). So, R124 + R239 equals R363. Therefore, Mary originally had R363 in her savings account. Now, if you’re ever in a similar situation, remember to always check your calculations twice! A common mistake is forgetting to add or subtract correctly, which can lead to confusion. Always writing down your steps helps keep things clear!
