- Armand, Ella, and Amber spent 15 hours collaborating on a study. Amber worked twice as long as Ella, and Ella worked 30% less than Armand. How many hours did Amber work?
- Let Ella = *x*.
- Armand = *x* / 0.7 (since Ella worked 30% less → working 70% of Armond’s time → 0.7Armand = x → Armand = x / 0.7 ≈ 1.4286x).
- So Armand = (1/0.7)x ≈ 1.4286x.
- Total: x + (x / 0.7) + 1.4286x ≈ x + 1.4286x + 1.4286x = 3.8572x = 15.
- x = 15 / 3.8572 ≈ 3.88.
