Arianna has $4 to spend at the candy shop she wants at least 10 sour snaps which are 15 cents each and at least 3 chocolate truffles which are 80 cents each. which system of inequalities correctly represents the sour snaps and t represent the chocolate truffles.

We are given the following information:
Arianna has $4 or 400 cents to spend.
Also, Arianna wants
(b) at least 10 snaps at 15 cents per snap,
(c) at least 3  ruffles at 80 cents each.

Let x =  the actual number of snaps purchased.
Let y =  the actual number of ruffles purchased.

In order to have at least 10 snaps and 3 ruffles,
x + y ≥ 10 + 3
Therefore
x + y ≥ 13                 (1)

In order to spend no more than 400 cents ($4),
15x + 80y ≤ 400       (2)

The two relations (1) and (2) represent the system of inequalities that should be satisfied.

x + y ≥ 13        
15x + 80y ≤ 400
where
x = number of snaps,
y = number of truffles.
