Question

This is the rule for how much fabric she needs to buy. • Measure from your waist to the finished length of the pants • Double this measurement • Add 8 inches 1. Amy's measurement from her waist to the finished length of the pants is 35 inches. How many inches of fabric does she need?

Answer 1

Answer:

She needs 78 inches of fabric.

Step-by-step explanation:

The rule for the amount of fabric that needs to be bought is:

$\text{fabric} = 2*x + 8$

Where "x" is the distance from the waist to the finished length of the pants. Since Amy's is 35 inches, the amount of fabric is:

$\text{fabric} = 2*35 + 8\\\text{fabric} = 70 + 8\\\text{fabric} = 78 \text{ inches}$

She needs 78 inches of fabric.
