Compare price per ounce.
31 oz at $2.53: 2.53 ÷ 31 ≈ $0.0816/oz
64 oz at $5.05: 5.05 ÷ 64 ≈ $0.0789/oz
The 64‑ounce bottle is cheaper per ounce (about $0.0789 vs $0.0816), saving ≈ $0.0027 per ounce — about $0.17 if you buy 64 oz. So the 64‑ounce bottle is the better buy. (Unless you’ll waste unused ketchup before it’s used up.)
