Answer:
t=312 minutes or t=5.2hrs
Step-by-step explanation:
I.Given that Stephanie has 6 classes a day of 52 minutes each.
-To get the duration spent in class each day, we multiply the total number of classes per day by the duration per class:

Stephanie spends 312 minutes per day in class
II. Get the duration in Hours:
#We multiply the class duration by number of class then divide by 60 minutes to get total duration in hours:

Stephanie spends 5.2hrs per day in class
7 * 2.9
(7 * 2) + (7 * 0.9) = 20.3 <==
The equations would look like this:
y = 0.10x + 30m
y = 50m
Y = total
x = per text message
m = number of months.
Hope this helps!!!
Y > .5x + 2
