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:

Step-by-step explanation:

He has 435 stamps in his collections.

He will collect d stamps, and he wants to collect at least 815 stamps, that is, the sum of 435 and d has to be at least 815.

So the inequality is given by:

And the answer is given by:

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square
