Option E
The person used the phone for 20 minutes that month
<em><u>Solution:</u></em>
Given that phone company charges customers a monthly charge using the equation:
C = 40 + 0.3m
Where,
"C" is the monthly charge in dollars
"m" is the number of minutes used by the customer
Someone's monthly charge is $46
To find: number of minutes used by that person
Therefore, given C = 46
Substitute C = 46 in given equation
46 = 40 + 0.3m
40 + 0.3m = 46
0.3m = 46 - 40
0.3m = 6
Thus the person used the phone for 20 minutes that month

Answer:
The equation that models this scenario
Step-by-step explanation:
First we convert 50 cent into dollar,
1 cent = dollar
1 cent = 0.01 dollar
50 cent = 0.5 dollar
According to question,
x is the number of 50¢=$0.5 price increases.
b(x) is the revenue generated
He currently charges $3 per book.
i.e. price of book = 3+0.5x
Quantity or average = 38 per day
According to a study, for every 50¢ increase in rental price, the average business can expect to lose 4 rentals a day.
i.e. quantity became 38-4x
Revenue = Price × Quantity
The required equation is given by,
