Your balance is $42. you buy lunch every day for $1.80 and sometimes buy a snack for $0.85. after 20 days you have a balance of $0.05. how much snacks did you buy?

The answer to your question is: I bought 7 snacks

Step-by-step explanation:

Data

beginning balance = $42 = b

lunch = $1.80  = l

snack = $ 0.85  = s

final balance = $0.05 = f

                       f = b - 1.8l - 0.05s

                    0.05 = 42 - 1.8l - 0.85s

After 20 days I spent = 1.8(20) in lunches = $36

                   0.05 = 42 - 36 - 0.85s

                  0.05 = 6 - 0.85s

                 0.05 - 6 = -0.85s

                 -5.95 = -0.85s

                 s = -5.95/-0.85

                 s = 7
