Cost of 8 books = 8*w = $ 8w
Cost of 7 pens = 7*m = $ 7m
Total money spent = 8w + 7m = $ (8w + 7m)
Money left = $ (3w + 5m)
Total initial money = Money left + money spent = 8w + 7m + 3w + 5m = 11w + 12m
= $ (11w + 12m)

Answer:
$ (11w + 12m)
Step-by-step explanation:
Cost of 8 books = 8*w = $ 8w
Cost of 7 pens = 7*m = $ 7m
Total money spent = 8w + 7m = $ (8w + 7m)
Money left = $ (3w + 5m)
Total initial money = Money left + money spent = 8w + 7m + 3w + 5m = 11w + 12m
= $ (11w + 12m)
