Answer: He has to save at least $420.

Step-by-step explanation:

Hi, to answer this question we have to write an inequality using the information given:

The amount he has already saved (75) plus the money he still needs to save (x) must be higher or equal to the cost of the Smartphone and accessories.

75 + x ≥ 495

Solving for x:

x ≥ 495-75

x ≥ 420

He has to save at least $420.
