You do the following.
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.
