To estimate the total earnings from selling dumplings, let's first determine how many plates of dumplings were sold.
-
Calculate the number of plates sold: \[ \text{Number of plates} = \frac{\text{Total dumplings}}{\text{Dumplings per plate}} = \frac{85,248}{12} \] \[ \text{Number of plates} \approx 7,104 \]
-
Calculate total earnings: \[ \text{Total earnings} = \text{Number of plates} \times \text{Price per plate} = 7,104 \times 9.89 \] \[ \text{Total earnings} \approx 70,000 \]
To be more precise: \[ 7,104 \times 9.89 \approx 70,198.76 \]
The closest estimate from the provided options for the total earnings is 80,000.
So the best estimate of the shop's total earnings from selling dumplings is 80,000.
