Question 135057
number of half dollars:  h
number of quarters: q


value of h half dollars: 50h cents
value of q quarters: 25q cents


Total money: $13.75, which can be expressed as 1375 cents, so:


50h + 25q = 1375


5 more half dollars than quarters:  h = q + 5, so:


50(q + 5) + 25q = 1375


Can you solve it from here or do you need more help?
