41.803 is 42 rounded to the nearest whole number because when you go past .5 you round to the nearest highest number, but when your below .5 then you round to the nearest lowest number.
The number of units produced by the worker during t hours of work can be modelled by the following function:

To find the number of units produced during first 3 hours, we can substitute 3 for t. This will give us the number of units produced by the worker during first 3 hours.

Thus the worker will produce 67 units during the first 3 hours of the work.
5x$12=$60 (spent on scarves)
2x5=10 (no of scarves in all)
$125-$60=$65 (total spent on scarves)
$65÷10=$6.50
Ans: $6.50
