Question

A teacher is making tutus for the school play. She wants to make at least 24 tutus and needs 1.25 yards of tulle for each tutu.

Write an inequality that can be used to determine the amount of tulle, x, the teacher needs to buy

Answer 1

x ≥ 30

Explanation:

The teacher wants to make at least 24 tutus. If each tutu requires 1.25 yards of tulle, then she will need to buy at least (1.25 × 24) yards of tulle. 1.25 yards × 24 is 30 yards.

The teacher will need at least 30 yards of tulle. In inequality form, this is x ≥ 30.
