Bob and his dad visited the hardware store on Saturday. They observed the following transactions:
Mr. Harris bought 4 for $0.50, Mrs. Clarke bought 21 for $1.00, Mr. Montaro bought 1,134 for $2.00, and Ms. Park bought 450 for $1.50. What were they buying?

With the limited data, it is impossible to tell. Repost with adequate data.

House Numbers, at 50 cents each. Mrs. Clarke bought the number 21, which is 2 pieces and therefore costs a dollar. Same with the others.
