Answer:
[tex]3b^2+2b\geq 56[/tex]
Step-by-step explanation:
Here, b represents the number of boxes she purchased for this upcoming school year,
Also, The number of markers in each box is two more than three times the number of boxes she purchased for this upcoming school year.
⇒ The number of marker in each box = 3b+2
Now, the total number of marker = Number of boxes × Number of marker in each box
[tex]=b\times (3b+2)[/tex]
[tex]=3b^2+2b[/tex]
Since, she plan to use at least 56 marker in the upcoming year,
That is, the total number of marker ≥ 56
[tex]\implies 3b^2+2b\geq 56[/tex]
Which is the required inequality that shows the given situation.
