Question

A box of cereal must weigh more than 629 g and less than 633 g to pass inspectionThe box in which the cereal is packaged weighs 5 g What are the possible weights for the cereal only?

Answer 1

Answer: 625g ,626g ,627 g

Explanation:

Hi, to answer this question we have to write an inequality:

The weight of the cereal (x) plus the weight of the box (5) must be higher than 629 and less than 633.

Mathematically speaking:

629<5+x<633

Solving for x:

629 <5+x

629-5 <x

624<x

5+x<633

x<633-5

x<628

624<x<628

So, the weight of the cereal only must be higher than 624g and less than 628g.

The possible weights are

625g ,626g ,627 g
