I️ think I️ can help.
Alice made 60 coasters, so if you divide 2 divided by 5, it would be 0.4, how much she spent on each, 0.4 times 60 is $24. Then, she had 60 coasters and if you divide them by 2, you will get 30 pairs of 2 coasters. 30 times five would mean she earns $150. Her cost was $24, so $150-$24=$126.
I️ hope that helped.
