Analyzing One-Variable Inequalities in Context

The lowest and highest temperature of a camel can be found by subtracting and adding the fluctuation to the normal body temperature $$\begin{array}{c}\text{normal ∘C}-\text{fluctuation ∘C}=\text{lowest ∘C}\\ \text{normal ∘C}+\text{fluctuation ∘C}=\text{highest ∘C}\end{array}$$ We can now use the values of the normal temperature and the fluctuation to calculate the lowest and highest temperature. $$\begin{array}{c}\text{Lowest: }37^{\circ }\text{C}-3^{\circ }\text{C}=34^{\circ }\text{C}\\ \text{Highest: }37^{\circ }\text{C}+3^{\circ }\text{C}=40^{\circ }\text{C}\end{array}$$ The range of actual body temperature of a camel is between $34^{\circ }\text{C}$ and $40^{\circ }\text{C}.$ To write an inequality of this, the temperature $x$ should be greater or equal to $34^{\circ }$ and less and equal to $40^{\circ }.$ $$34^{\circ }\text{C}\le x\le 40^{\circ }\text{C}$$
