Answer: B

Step-by-step explanation:

Equation A:

15x - 45 = 75x + 75

=> -120 = 60x

=> x = -2

Equation B:

15x - 45 = 15x + 75

=> 0 = 15

<em>No Solutions</em>

<em />

Equation C:

45x - 45 = -15x + 75

=> 60x = 120

=> x = 2

Equation D:

-45x - 45 = -75x + 75

=> 30x = 120

=> x = 4

Customers of a phone company can choose between two service plans for long distance calls. The first plan has no monthly fee but
hram777 [196]

Answer:

\\x= P/(c -d)[/tex],

Assume that the price of each minute in the first plan is $c and that the second plan charges a flat rate of $P and a charge  of additional $d for every minute.

Step-by-step explanation

Assume that the price of each minute in the first plan is $c and that the second plan charges a flat rate of $P and a charge  of additional $d for every minute.

Thus, the monthly cost of a customer who consumes x minutes in each plan is:

For the first plan: cx

and for the second plan: P + dx

Considering that the monthly costs must be the same in each plan, you have to:

cx = P + dx\\ transposing terms\\cx - dx = P\\   applying common factor\\(c -d)x = P\\ dividing by [tex]c - d

\\x= P/(c -d)[/tex].

For example if c = $2; d = $1 y P = $10, Then the number of minutes would be, x=10  and the total cost for each plan would be $20
