Two phone companies one is 11/+.16/ min And another is 20+.11/min How many minutes will make both equal amounts
Ilia_Sergeevich [38]

Answer:

Company one charges $11 + $0.16 per min.

Then if you talk for x minutes, the cost will be:

C₁(x) = $11 + ($0.16 per min)*x

For company two, the prize is $20 + $0.11 per min, and if yo talk for x minutes, the cost will be:

C₂(x) = $20 + ($0.11 per min)*x

Now we want to find the value of x, the number of minutes, such that the cost is the same with both companies.

C₁(x) = C₂(x)

$11 + ($0.16 per min)*x = $20 + ($0.11 per min)*x

($0.16 per min)*x - ($0.11 per min)*x = $20 - $11

($0.05 per min)*x = $9

x = $9/($0.05 per min) = 180 mins

If you speak for 180 minutes, the cost is the same in both companies.

( 5x + 685 ) + ( 12x - 106 ) = 2500
uysha [10]

Answer:

            x  = 113

Step-by-step explanation:

( 5x + 685 ) + ( 12x - 106 ) = 2500                                          ( 685 - 106 =   579)

                       17x  +  579 = 2500

                             17x        = 2500 - 579

                                    17x =     1921

                                       x = 1921 / 17

                                      x  = 113
