Final answer:
The correct answer is not listed among the options because the total weight of fruit Sam and Maria have together is 1800 grams plus Maria's weight of fruit in grams, which is h times 454.
Step-by-step explanation:
The correct answer is option 'b'. To determine the total weight of the fruits, we first need to convert Josh's purchases into the same unit of measure, which in this case is grams. Josh bought 1.5 kilograms of oranges, and since 1 kilogram is equal to 1000 grams, this is equivalent to 1500 grams. He also bought 150 grams of grapes, and this weight does not need conversion. Lastly, he bought 15,000 centigrams of apples. There are 100 centigrams in a gram, so 15,000 centigrams converts to 150 grams of apples.
Now, we add the weights of the three types of fruit together:
- Oranges: 1500 grams
- Grapes: 150 grams
- Apples: 150 grams
1500 grams + 150 grams + 150 grams = 1800 grams of fruit in total.
Maria has h pounds of fruit. To find out how much that is in grams, we need to know that 1 pound is equivalent to 454 grams. Therefore, Maria has h × 454 grams. To find the total weight of the fruit that Sam and Maria have together, we add Joshua's and Maria's total weights in grams:
1800 grams + (h × 454 grams)
Since we do not have a specific value for h, the answer does not correspond to any of the given numeric options, as they cannot be correct without knowing the value of h.
