As a small step to save the environment, Luna came up with an idea for her sweet shop. In exchange for five eclaire boxes, that she gets, she decided to give an eclaire box for free. A group of kids from the locality ate seventy-seven eclaire boxes that week and they collected the boxes to give to Luna and get back eclaires boxes. How many eclaires boxes do you think they can buy from Luna using the seventy-seven claire boxes?

Kids will get 15 eclaire boxes in the exchange of 76 boxes.

Step-by-step explanation:

Exchange criteria:

1 Ecalaire box free for 5 eclaire boxes.

Total boxes collected by kids =76

Number of eclaire boxes they will get = 76 ÷5

= or 15 (approx.)

i.e. they will get 15 eclaire boxes in the exchange of 76 boxes.
