The system of equations that can be used to determine the rates of each type of service are:
45x + 50y = $27.75
70x + 30y = $36.
<h3>What are simultaneous equations?</h3>
Simultaneous equations are sets of equations that have to be solved together or at the same time in order to determine the required values. The two above equations have to be solved together in order to determine the cost of the peak and nonpeak services.
The methods that can be used to solve simultaneous equations are:
- Graph method
- Substitution method
- Elimination method
Here is the complete question: The price of a cellular telephone plan is based on peak and non-peak service. Kelsey used 45 peak minutes and 50 non-peak minutes and was charged $27.75. That same month, Austin used 70 peak minutes and 30 non-peak minutes and was charged $36. Write a system of equations that can be used to determine the rates for each type of service.
Use x for peak minutes and y for non-peak minutes.
