Consumer Math Help:
Purchase Price per 100 Shares: ABC: $425 DEF: $600
Commission: ABC: 0 DEF: 375
Total Cost: ABC: 425 DEF: 975
Sales Price: ABC: 637.50 DEF 900
Commission: ABC: 0 DEF: 0
Cash to Tim= Sales Price-Commission: ABC: 637.50 DEF= 900
Cash to Tim/Total Cost: ABC: 150% DEF: 92%
If Tim does not buy DEF, how much can he spend on ABC?
How many shares of ABC can he buy if he does not buy DEF (nearest tenth)?
If you can explain this then you're my hero I've been stuck on it for days now. And there's another one similar to it, so if you explain that's great!
