(a)
Total number of games if all are card games
= 17 x 25
= 425
Big difference between the number of boxes of card games and boxes of board games
= 425 - 269
= 156
Small difference between the number of 1 box of card games and 1 box of board games
= 17 - 5
= 12
Number of boxes of board games
= 156 ÷ 12
= 13
Total number of board games
= 13 x 5
= 65
(b)
Total cost of board games
= 65 x 18
= $1170
Total cost of card games
= 2190 - 1170
= $1020
Answer(s): (a) 65; (b) $1020
