many of these boxes do you need to buy?you need to buy 40 packsExample 2.At a restaurant one day. 60 sandwiches were sold in all, some on rye bread and 28 onwhite bread. The number of sandwiches sold on try bread was twice the number soldthe day before. How many sandwiches on rye bread were sold the day before"?

Answer 1

rye bread sandwiches + white bread sandwiches = total number of sandwiches

rye bread sandwiches + 28 = 60

rye bread sandwiches = 60 - 28

rye bread sandwiches = 32

This number, 32, is twice the day before, that is, the day before was half of 32 sandwiches, which is 32/2 = 16.

The day before, 16 sandwiches on rye bread were sold.
