We have the following variables:
chips (x)
salsa (y)
The inequality in this case is given by:
2.5x + 4y <= 60
For x = 10, y = 2:
2.5 (10) + 4 (2) <= 60
25 + 8 <= 60
33 <= 60
For x = 20, y = 2:
2.5 (20) + 4 (2) <= 60
50 + 8 <= 60
58 <= 60
For x = 14, y = 5:
2.5 (14) + 4 (5) <= 60
35 + 20 <= 60
55 <= 60
For x = 18, y = 6:
2.5 (18) + 4 (6) <= 60
45 + 24 <= 60
69 <= 60
The inequality is not fulfilled.
Answer:
18 bags of chips and 6 jars of salsa
