13,257 + 5(13,257) = 79,542
79,542/109 = 729  full boxes with a remainder of 81 toys ..so 730 boxes
find total
cars+trucks=ttoal
total/numberofcarsperbox<numberofboxes

13257+5*13257=79542
79542/109=729.7
round up since you can't ship 0.7 box

730 boxes
(techincally 729 boxes can be FILLED, but 730 boxes are needed)
