To find out how much Karen saved last week, we can follow these steps:
Step 1: Set up an equation.
Let's assume the amount Karen saved last week is x.
According to the given information, the amount she saved this week is $200.00.
We are also told that this amount is $50.00 more than twice the amount she saved last week.
So, we can set up the equation:
200 = 2x + 50
Step 2: Solve the equation.
To solve the equation, we need to isolate x.
First, subtract 50 from both sides of the equation:
200 - 50 = 2x
150 = 2x
Next, divide both sides of the equation by 2:
150/2 = x
75 = x
Step 3: Interpret the answer.
The result of the equation tells us that Karen saved $75.00 last week.
Therefore, Karen saved $75.00 last week.
