Nelly's Nails came out with 19 new colors of nail polish. One store ordered 6 bottles of each color.

The store manager worked out that they ordered 114 bottles of nail polish. Does that sound about right?

Yes — that is correct.

Exact: 6 × 19 = 6 × (20 − 1) = 120 − 6 = 114 (or 60 + 54 = 114).

Estimate: 19 ≈ 20, and 20 × 6 = 120, so 114 is very close to the estimate and sounds reasonable.
