Question

Alfonso has 435 stamps in his collection. He wants to collect at least

Answer 1

Answer:

Inequality: $435 + d \geq 815$

Solution: $d \geq 380$

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:

$435 + d \geq 815$

And the answer is given by:

$d \geq 815 - 435$

$d \geq 380$
