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?
To determine what Bob and his dad observed people buying at the hardware store, let's analyze the given transactions:
1. Mr. Harris bought 4 for $0.50: This means that Mr. Harris purchased four items for a total of $0.50. To find out what he bought, we need to divide the total price by the quantity. So, $0.50 / 4 = $0.125 per item. Therefore, Mr. Harris bought four items of something at $0.125 each.
2. Mrs. Clarke bought 21 for $1.00: Following the same process, we divide the total price by the quantity. $1.00 / 21 = $0.0476 per item. This means that Mrs. Clarke bought twenty-one items at $0.0476 each.
3. Mr. Montaro bought 1,134 for $2.00: Dividing the total price by the quantity, we get $2.00 / 1134 ≈ $0.0018 per item. Therefore, Mr. Montaro bought 1,134 items at approximately $0.0018 each.
4. Ms. Park bought 450 for $1.50: By dividing the total price by the quantity, $1.50 / 450 ≈ $0.0033 per item. Thus, Ms. Park bought 450 items at approximately $0.0033 each.
Based on the above calculations, we can see that the items people were buying at the hardware store are not explicitly mentioned or specified. Additional information is needed to determine what exactly Mr. Harris, Mrs. Clarke, Mr. Montaro, and Ms. Park were purchasing.
