(a)
Total number of games if all are card games
= 17 x 24
= 408
Big difference between the number of boxes of card games and boxes of board games
= 408 - 268
= 140
Small difference between the number of 1 box of card games and 1 box of board games
= 17 - 7
= 10
Number of boxes of board games
= 140 ÷ 10
= 14
Total number of board games
= 14 x 7
= 98
(b)
Total cost of board games
= 98 x 16
= $1568
Total cost of card games
= 2758 - 1568
= $1190
Answer(s): (a) 98; (b) $1190
