The equation is 51 = x + 120 × 0.30 that can find the monthly base fee charged by Chitchat wireless.
The equation representing the scenario will be formed through following components.
Total bill = monthly base fee + number of minutes × cost per minute
In the above mentioned equation, let us assume the monthly base fee to be x. Now, keep the values in formula to find the value of x.
51 = x + 120 × 0.30
Performing multiplication on Right Hand Side of the equation
51 = x + 36
Rewriting the equation according to x
x = 51 - 36
Performing subtraction on Right Hand Side of the equation
x = 15
Thus, the monthly base fee is $15.
