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.
