aev [14]

Answer:

The temperature at the base camp Friday evening is - 6 degrees Celsius.

Step-by-step explanation:

To get the temperature at a mountain base camp on Friday evening, we must translate statement into a mathematical form:

(i) <em>The temperature at a moutain base camp was - 2 degress Celsius on Thursday</em>:

T_{o} = -2\,^{\circ}C

(ii) <em>Friday morning, the temperature was 1 degree Celsius lower than it was on Thursday</em>:

\Delta T_{1} = -1\,^{\circ}C

(iii) <em>Friday evening, the temperature was 3 degrees Celsius lower that it was that morning</em>:

\Delta T_{2} = -3\,^{\circ}C

The temperature at the base camp Friday evening is:

T = T_{o}+\Delta T_{1}+\Delta T_{2}

T = -2\,^{\circ}C-1\,^{\circ}C-3\,^{\circ}C

T = -6\,^{\circ}C

The temperature at the base camp Friday evening is - 6 degrees Celsius.
