A cellphone company charges $60 for a cellphone and a monthly rate to use the phone.Regina will pay $1,140 for a 24-month cellph
Alinara [238K]

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

24m+60=1140\\24m=1140-60\\24m=1080

Dividing both sides by 24

\frac{24m}{24}=\frac{1080}{24}\\m=45

The monthly rate is $45 for this cellphone plan.
