<h3><u>
Answer:</u></h3>
Hence, the number of cans collected is increasing linearly.
<h3><u>
Step-by-step explanation:</u></h3>
The table that represent the collection is given by:
Day Cans Collected
------------------|---------------------
1 15
------------------|---------------------
2 20
----------------------------------------
3 25
----------------------------------------
4 30
----------------------------------------
5 35
----------------------------------------
6 40
The number of cans is increasing by a constant term that is five each day.
It could be modeled by the function:
f(t+1)=f(t)+5
where t represent the number of days.
the initial amount i.e. f(1)=15 cans.
Hence, the number of cans collected is increasing linearly.
