Your cell phone company Offers you a choice between two promotional deals you can either get 500 free text messages with the charge of $.10 for each text message over 500 or you can get 400 text messages with a charge of $.20 for each text message over 400 how many text messages would you have to send for the cost to be the same for either Plan?

The number of messages that will cost same both plans is 1000.

Step-by-step explanation:

Given,

For 1st offer:

Total number of messages = 500

Charge of each message after 500 messages = $0.10

For 2nd offer:

Total number of messages = 400

Charge of each message after 400 messages = $0.20

We need to find out the number of messages can be sent for equal cost of both plans.

Solution,

Let the number of messages be 'm'.

So For 1st offer:

Total cost 'c' is equal to fixed cost for 500 messages plus charge of each message multiplied with number of messages.

framing in equation form, we get;

Again for 2nd offer:

Total cost 'c' is equal to fixed cost for 400 messages plus charge of each message multiplied with number of messages.

framing in equation form, we get;

Now the question said that the charge would be the same.

So we can say that;

On combining the like terms, we get;

Now using multiplication property, we will multiply both side by '10' and get;

Hence The number of messages that will cost same both plans is 1000.
