Alfonso has 435 stamps in his collection. He wants to collect at least 815 stamps. Write and solve an inequality to determine how many

more stamps Alfonso must collect to reach his goal. Let d represent the

number of stamps Alfonso must collect to reach his goal.

435 + d-815; d-380

435 + > 815;d > 380

435 + d 2815;d > 815

435 +0 2 815; d 2380

Inequality:

Solution:
