Alright, so we know that Alex purchased a 6-hour calling card. We also know that our answer has to use the variable t to represent how many minutes he has left. So now we have to figure out how many minutes our in 6 hours:

First, we know that there are 60 minutes in a single hour. If we have 6 hours, what can we do to find how many minutes are in that? Multiplication. We can multiply the 60 minutes in a single hour by the 6 hours to get the total amount of minutes in 6 hours, which is t:
\[6*60=t\]
As for the units, those really don't matter when trying to solve it. But just for the sake of it, it would look more like this:


Hope that helps!
