Under plan a a 2 minute call costs .54 cents a 4 minute call costs 1.08. under plan b the cost for x minutes is given by y=0.289x. which plan is cheaper? why?

Plan A is cheaper, because the cost of a 2-minute call and a 4-minute call is less than the cost of a 2-minute call and a 4-minute of Plan B call.

Step-by-step explanation:

1. You have the following information of Plan A:

- A 2 minute call costs .54 cents.

- A 4 minutes call costs $1.08.

2. For Plan B, you know that the cost of is given by the equation:

3. Therefore, you can compare both plans by finding the cost of a call of 2 minutes and a call of 4 minutes of Plan B. You can calculate this by giving these values to :

4. Substitute the values into the equation:

(This is more expensive)

(This is more expensive)

5. Therefore, Plan A is cheaper, because the cost of a 2-minute call and a 4-minute call is less than the cost of a 2-minute call and a 4-minute of Plan B call.

the correct answer would be:

220 centimeters

to get this you can use the pythagorean theorem
