The monthly rate is $45 for this cellphone plan.
Step-by-step explanation:
Given,
Amount charged for cell phone = $60
Amount paid by Regina for 24 month plan = $1140
Number of months = 24
Let,
m be the monthly rate for cellphone plan
Number of months * Monthly rate + cellphone charges = Amount paid
[tex]24m+60=1140\\24m=1140-60\\24m=1080[/tex]
Dividing both sides by 24
[tex]\frac{24m}{24}=\frac{1080}{24}\\m=45[/tex]
The monthly rate is $45 for this cellphone plan.
