The answer 45 and the other one to the question is invalid
4a+2-3c+6+7c-3-3b+2a-5b you can combine 4a and 2a to get 6a
6a+2-3c+6+7c-3-3b-5b you can combine 5b and 3b to get -8b
6a+2-3c+6+7c-3-8b you can combine 3 and 2 and 6 to get 5
6a+5-3c+7c-8b you can combine 3c and 7c to get 4c
6a+5+4c-8b
Profit = revenue - expenses
250 = 25x - (12x + 60)
250 = 25x - 12x - 60
250 = 13x - 60
250 + 60 = 13x
310 = 13x
310/13 = x
23.85 = x....so she would have to sell 24 purses
