A. 38.5°C
Explanationas Mar´s temperature goes 1.5 °C higher , we need to add 1.5 ° to the normal body temperature to obtain Mark´s temperature
so
Step 1
a)let
[tex]\begin{gathered} Normal\text{ body temperature=37\degree} \\ Mark^{\prime}s\text{ temperature=Normal body temperature +1.5 \degree C} \end{gathered}[/tex]replace
[tex]\begin{gathered} Mark^{\prime}s\text{temperature=Normalbodytemperature+1.5\operatorname{\degree}C} \\ Mark^{\prime}s\text{temperature=37\degree+1.5}\operatorname{\degree}\text{C} \\ Mark^{\prime}s\text{temperature=38.5 \degree} \end{gathered}[/tex]therefore, the answer is
A. 38.5°C
