Answer:
D. 75m = 50(12)+125(m-12)
Step-by-step explanation:
m = months.
Equation for which Plans A and B cost the same.
In Plan A:
No initial fees.
$75 per month
1 month = $ 75
then;
for m month =$75 m
Total cost for plan A = 75m
In Plan B:
$50 per month for first 12 month.
1 month = $50
12 months = 50(12)
Similarly,
$125 per month for each additional month after that.
additional month= (m-12)
Plan B additional month
= 125(m-12)
Total cost for plan B = 50(12)+ 125(m-12)
Since, Plans A and B cost the same.
75m = 50(12)+125(m-12)
3x+60=150 can be used to determine the number of days you read. Solving the equation determines that you have been reading for 30 days.
Step-by-step explanation:
Total pages = 150
Pages per days = 3
Pages left to read = 60
Let,
x be the number of days.
According to given statement;
Total pages = Pages per day*number of days + Pages left to read

Dividing both sides by 3

3x+60=150 can be used to determine the number of days you read. Solving the equation determines that you have been reading for 30 days.
