The compound inequality will be: , where is the mass of a single pencil and each pencil can have a mass of 10.5 grams.
<em><u>Explanation</u></em>
Suppose, the mass of a single pencil in the pack is gram.
So, <u>the total mass of 5 pencils</u> will be: grams.
Each package has a mass of 15 grams. So, the <u>total weight of the pack of 5 pencils</u> grams.
To be within the weight specifications, a pack of 5 pencils should weigh <u>between 60 grams and 95 grams</u>. So, the compound inequality will be..........
So, the compound inequality to represent the mass of a single pencil in a pack will be: , where is the mass of a single pencil.
- <u>As 10.5 grams lies inside the interval</u> , so each pencil can have a mass of 10.5 grams.
