<u>Part A: </u>

Write and solve an inequality to represent the number of cans, c, that Jacob must still collect.

Jacob has collected 64 cans . Jacob need to collect at least 120 cans for a food drive to earn community service credit , Let Number of cans that Jacob have to collect is c , So following is the inequality for above scenario:

⇒ c+64\geq 120

⇒ (c+64)-64\geq 120-64

⇒ c\geq 56

Therefore , An inequality that represent  the number of cans, c, that Jacob must still collect is  c\geq 56 .
