A temperature starts at \(6^{\circ}\text{C}\) and changes by \(-1.5^{\circ}\text{C}~\text{per}~\text{hour}\) for \(8~\text{hours}\). Write the total-change expression and the final-temperature equation.

8(-1.5) = -12°C; 6 - (-12) = 18°C

8(-1.5) = -12°C; 6 + (-12) = -6°C

6 + (-1.5) = 4.5°C

8(1.5) = 12°C; 6 + 12 = 18°C
