A paper bag can hold 16 cookies. If Edgar buys 292 cookies,
a) How many paper bags does he need?
b) How many cookies are there in the paper bag that is not full?
292 ÷ 16 = 18 r 4, so there are 18 paper bags with 16 cookies each and 1 paper bag with 4 cookies,
a) 18 + 1 = 19 paper bags are needed.
b) There are 4 cookies in the paper bag that is not full.
