Explanation:
The way this is written, everything after the words "divided by" would be calculated first; it is written as though this is a grouping, such as 20/(2*(5+5)). We would evaluate the innermost parentheses first; 5+5=10. Then this gives us 2*10=20 in our parentheses. 20/20 = 1.</span>

Let $k = the monthly base fee.
The variable cost is $0.30 per minute.
Let
C = total cost in a month
x = minutes used
September:
x = 120 minutes
C = $50
Therefore
k + (0.30)(120) = 50
k + 36 = 50
k = $14
October:
x = 165 minutes
The cost is
C = 14 + (0.3)(165)
C = $63.5
Answer: $63.50
