Isabel is buying 6 angelfish, and she wants her total cost to be no more than $2 above below $36. write the inequality that will model the cost x in dollars of an anglefish

Respuesta :

From the problem, the total must not be more than $2 above or below $36

So the range must be from $34 up to $38 only

Let x be the cost of 1 angelfish, and the total cost for 6 angelfishes is 6x

The inequality will be :

[tex]34\le6x\le38[/tex]

Divide both sides by 6 :

[tex]\begin{gathered} \frac{34}{6}\le\frac{6x}{6}\le\frac{38}{6} \\ 5.67\le x\le6.33 \end{gathered}[/tex]

The answer is $5.67 ≤ x ≤ $6.33
