Answer:
5 red chairs for $91.40
Explanation:
"Unit price is the price for a single unit of measure of a product sold in more or less than the single unit. The "unit price" tells you the cost per pound, quart, or other unit of weight or volume of a food package."
4 blue chairs for $73.48 ÷ 4 = $18.37
5 red chairs for $91.40 ÷ 5 = $18.28
Therefore, 5 red chairs have a smaller unit price.
