Answer:
42
Step-by-step explanation:
To find out how many widgets he made, you need to find out how much money was earned from all the widgets he made. You know that one day only earns $150 without any widgets but the factory worker earned $370.50 so the difference would be the amount of money earned from the extra widgets.
Amount of money earned from widgets = $370.50 - $150
= $220.50
You know each widget costs $5.25, so you can find out how many widgets were made.
No. of widgets made = $220.50 ÷ $5.25
= 42
