Final answer:
To find the cost per pineapple, multiply the number of buckets by pineapples per bucket, then divide the total cost by the total number of pineapples and round to the nearest cent. The result is $0.43 per pineapple, but based on the given options, the closest is $0.42 (option a).
Step-by-step explanation:
To calculate the cost per pineapple, we first need to determine the total number of pineapples sold. Since the grocery store sells 22 buckets and each bucket contains 21 pineapples, we multiply these two numbers to get the total pineapples.
- Multiply the number of buckets by the number of pineapples per bucket: 22 buckets × 21 pineapples/bucket = 462 pineapples.
- Divide the total cost by the total number of pineapples to find the cost per pineapple: $198 ÷ 462 pineapples = approximately $0.4285 per pineapple.
- Round this amount to the nearest cent: $0.43 per pineapple.
However, since the answer options provided are in increments of $0.03, rounding to the nearest option given would result in $0.42 per pineapple (option a).
