Answer:
The practical range is all whole numbers from 480 to 1200, inclusive Step-by-step explanation:
Given :
Clarence sells the yearly subscriptions to a particular magazine and he sells atleast 10 subscriptions and they wont be more than 25 subscriptions in an each week.
If the function
f(t)=48 t
represents the amount of money earned for selling t subscriptions each week,
f(t) = 48 (10) =480
f(t) = 48(25) = 1200
the practical range of this function will be the set of all whole numbers including 480 to 1200
