To estimate the total earnings from selling dumplings, we first need to determine how many plates of dumplings were sold.
-
Calculate the number of plates sold: \[ \text{Number of plates} = \frac{\text{Total dumplings}}{\text{Dumplings per plate}} = \frac{85,248}{12} \approx 7,104 \]
-
Calculate the total earnings: \[ \text{Total earnings} = \text{Number of plates} \times \text{Price per plate} = 7,104 \times 9.89 \] To quickly estimate: \[ 7,104 \times 10 = 71,040 \quad \text{(a rough estimate)} \] But for more accuracy: \[ 7,104 \times 9.89 \approx 70,203.36 \]
From the answer choices you provided (8,000, 80,000, 800,000, 8,000,000), the closest estimate for total earnings is 80,000.
Thus, the answer is 80,000.
