To find out how much Gino will get paid for 40 hours of work, we first need to determine his hourly rate.
Gino earns $640 for 20 hours of work, so his hourly rate is calculated as follows:
\[ \text{Hourly Rate} = \frac{\text{Total Pay}}{\text{Total Hours}} = \frac{640}{20} = 32 \text{ dollars per hour} \]
Next, we can calculate how much Gino will earn for 40 hours of work:
\[ \text{Pay for 40 hours} = \text{Hourly Rate} \times \text{Hours} = 32 \times 40 = 1280 \text{ dollars} \]
Thus, Gino will get paid $1,280 for plowing for 40 hours.
The correct answer is:
$1,280
