Problem

Tuesday’s high temperature was 4 C warmer than that of Monday’s. Wednesday’s high temperature was 6 C cooler than that of Monday’s. If Tuesday’s high temperature was 22 C, what was Wednesday’s high temperature?

$\text{(A)} 20 \quad\text{(B)} 24\quad \text{(C)} 12\quad \text{(D)} 32 \quad \text{(E)} 16 \quad$

(all in Celsius)

Solution

Tuesday's high temperature was 22 C, so Monday's high temperature was 18 C and Wednesday's temperature was 12 C.

The answer is $\boxed{\text{(C)} \quad 12}.$
