Answer
154.2°
Explanation
the oven temperature drops 2 degrees every time 50 pills, then for 145 we have:
[tex]\frac{2}{50}=\frac{x}{145}[/tex][tex]x=\frac{145\cdot2}{50}=5.8[/tex]The iniial oven temperature is 160, so:
[tex]160-5.8=154,2[/tex]when this batch of pill production is finished the temperature will be 154.2°
