One cell phone company charges a $76 sign-up fee and $40 per month. Another cell phone company charges $136 sign-up fee and $20

WARRIOR [948]

Answer:

The cost would be same after 3 months.

Step-by-step explanation:

Given that:

Charges of first company;

Per month charges = $40

Let,

x be the number of months

y be the total cost.

y = 40x + 76 Eqn 1

Charges of second company;

Per month charges = $20

y = 20x + 136 Eqn 2

For same cost,

Eqn 1 = Eqn 2

40x + 76 = 20x + 136

40x-20x = 136 - 76

20x = 60

Dividing both sides by 20

$\frac{20x}{20}=\frac{60}{20}\\x=3$

Hence,

The cost would be same after 3 months.
