Question

Lisa bought 12 pieces of rope. Each rope was 3/4 of a meter long. If the rope cost $3.50 a meter, how much did she spend?

Answer 1

To find out how much Lisa spent on the rope, we can follow these steps:

1. **Calculate the total length of rope Lisa bought**:
Lisa bought 12 pieces of rope, each measuring \( \frac{3}{4} \) meter long. Thus, the total length is:
\[
12 \times \frac{3}{4} = 12 \times 0.75 = 9 \text{ meters}
\]

2. **Calculate the cost of the rope**:
The cost per meter of rope is $3.50. Therefore, the total cost is:
\[
9 \text{ meters} \times 3.50 \text{ dollars/meter} = 31.50 \text{ dollars}
\]

So, Lisa spent **$31.50**.
