Take the price of the most expensive subscription and retract the price of the cheap one.
$50-$40 = $10
Since we know what the price of a text message and the difference in dollars between the two subscriptions, we can calculate how many text messages has to be sent. We just divide the result from before ($10) with the price of a text message ($0.2)
$10/$0.2 = 50
The total number of text messages that needs to be send in order for the price of the subscriptions to be the same, is 50.

So the answer is No, Emma will not be receiving a free cupcake as she is the 17th customer and doesn't fall into the 4th customer pattern.
Answer:
If you solve a linear equation you have two different lines.
Now with that being said the solutions are as follows;
<u>One Solution</u>: The slopes are different
<u>No solution</u>: The slopes are the same and the y intercepts are different
<u>Infinite Solutions</u>: The slopes are the same and the y intercepts are different
