The equation 25x+1295=212000 models the situation. The bill had charges of 8428.2 minutes
Step-by-step explanation:
Given,
Monthly rate = $1295
Per minute charges = $25
Bill for x minutes = $212000
As x are the total minutes.
Per minute charges * Total minutes + Monthly rate = Bill for x minutes
25x+1295=212000
Dividing both sides by 25
The equation 25x+1295=212000 models the situation. The bill had charges of 8428.2 minutes

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
When we round to the nearest tenth, we need to look to the number in the hundredths place.
789.652
If the number is 4 or less, then we round down. If the number is 5 or more, then we round up.
Since '5' is 5 or more, we know to round up. So....
789.652 becomes 789.7
