16. Karen saved P200 this week from her allowance. If this amount is P50 more than twice the amount she saved last week, how much did she save last week?

Let's solve the problem step by step. **Given:** - Karen saved **P200** this week. - This amount is **P50 more** than **twice** the amount she saved last week. **Let's define:** - Let **\( x \)** be the amount Karen saved **last week**. **According to the problem:** \[ 200 = 2x + 50 \] **Step-by-Step Solution:** 1. **Set Up the Equation:** \[ 200 = 2x + 50 \] 2. **Subtract 50 from both sides to isolate the term with \( x \):** \[ 200 - 50 = 2x \] \[ 150 = 2x \] 3. **Divide both sides by 2 to solve for \( x \):** \[ \frac{150}{2} = x \] \[ x = 75 \] **Conclusion:** Karen saved **P75** last week.
