Using the trend line, what whole number could you infer the daily sales amount is when the temperature is 68 degree? Round your answer to the nearest whole number: 60 degree $24; 68 degree $44; 68 degree $54; 94 degree $80

To infer the daily sales amount at a temperature of 68 degrees, let's analyze the provided data points:

1. At 60 degrees, the sales are $24.
2. At 68 degrees, the sales are $44.
3. At another 68 degrees, the sales are $54 (this indicates there might be variability at the same temperature).
4. At 94 degrees, the sales are $80.

Since there are two entries for 68 degrees ($44 and $54), we can take the average of these two values to provide a more consistent estimate:

\[
\text{Average sales at 68 degrees} = \frac{44 + 54}{2} = \frac{98}{2} = 49
\]

Rounding $49$ to the nearest whole number, the inferred daily sales amount at 68 degrees is approximately **49**.
