Answer:
Yes
Step-by-step explanation:
Let's consider what Adrian does for a few weeks, that is, we will make a table where we can see the behavior of the savings with respect to the weeks that pass:
time (week) savings ($)
0 28
1 43
2 58
3 73
4 88
5 103
and if we continue doing we see that it has a similar behavior, and the equation would be:
s = 15 * m + 28
where s are the savings and m the number of months, which means that 15 is that constant of proportionality and therefore they are proportional.
