I'm giving brainliest to the right rai compares two cable plans from different companies. which equation gives the correct value of m, the number of months for which plans a and b cost the same? a)  75m=50+125(m−12)b)  75m=50(12)+125mc)75m=50(12)+(125m−1 2)d)  75m=50(12)+125(m−12)

Option  D is correct.

Step-by-step explanation:

Here, m represents the months.

We have to find the equation for which Plans A and B cost the same.

In Plan A:

No initial fees.

$75 per month.

For 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.

For 1 month = $ 50

for 12 months = 50(12)

Similarly for:

$125 per month for each additional month after that.

For additional month (m-12) = 125(m-12)

then

Total cost for plan B = 50(12)+125(m-12)

Since, Plans A and B cost the same.

⇒

Therefore, an equation gives the correct value of m, the number of months for which Plans A and B cost the same is,
