ORDER AND JUDGMENT *

Nadine Espinoza-Horiuchi sued Wal-mart, Inc. for employment discrimination. She appeals regarding two district court *592 orders. We lack jurisdiction to review the first order because the notice of appeal was untimely. We affirm as to the second order because the issue has been inadequately briefed, and Ms. Espinoza-Horiu-chi has otherwise not shown a ground for reversal.

First, the district court granted summary judgment for Walmart and issued a final judgment on December 27, 2016. On January 9, 2017, the court struck Ms. Espinoza-Horiuchi’s motion for reconsideration from the docket. She filed her notice of appeal on February 28, 2017. Because she filed the notice more than 30 days from entry of the judgment, we lack jurisdiction to review the grant of summary judgment. See 28 U.S.C. § 2107(a); Fed. R. App. P. 4(a)(1)(A); Bowles v. Russell, 551 U.S. 205, 208, 127 S.Ct. 2360, 168 L.Ed.2d 96 (2007).

Second, on February 23, 2017, the district court issued a bill of costs for Wal-mart for $848.80. Ms. Espinoza-Horiuchi’s February 28, 2017 notice of appeal mentions the bill of costs and therefore was timely filed for our review of this issue. The bill of costs ($848.80) covered the “[cjosts incident to taking of depositions” totaling $792.00 and <([o]ther expenses” totaling $56.80. ROA at 262. The district court attached copies of materials supporting these costs. Id. at 263-64. Ms. Espinoza-Horiuchi’s brief argues only that the “records of me going to court which were/ are irrelevant to the case and expected me to pay for the Bill of Costs for these records.” Aplt. Br. at 4 (emphasis in original). The brief does not specify which “records” were irrelevant or why they were irrelevant, and does not show why they district court may have erred in issuing the bill of costs. The issue is therefore inadequately briefed. See Birch v. Polaris Indus., Inc., 812 F.3d 1238, 1249 (10th Cir. 2015). Ms. Espinoza-Horiuchi has not otherwise demonstrated a ground for reversal.

Exercising jurisdiction under 28 U.S.C. § 1291, we dismiss the appeal of the summary judgment decision for lack of jurisdiction and affirm the district court’s bill of costs.
