(A) Let the temperatures on Monday,Tuesday,Wednesday,Thursday,and Friday be $M, T, W, Th,$ and $F$ respectively.The average temperature for Monday,Tuesday,Wednesday,and Thursday is $48^{\circ}$.So,$(M + T + W + Th) / 4 = 48$,which implies $M + T + W + Th = 48 	imes 4 = 192$.The average temperature for Tuesday,Wednesday,Thursday,and Friday is $52^{\circ}$.So,$(T + W + Th + F) / 4 = 52$,which implies $T + W + Th + F = 52 	imes 4 = 208$.Subtracting the first equation from the second:$(T + W + Th + F) - (M + T + W + Th) = 208 - 192$$F - M = 16$.Given that the temperature on Monday $(M)$ is $42^{\circ}$,we substitute this value:$F - 42 = 16$$F = 16 + 42 = 58$.Therefore,the temperature on Friday was $58^{\circ}$.

The average temperature for Monday,Tuesday,Wednesday and Thursday was $48^{\circ}$. The average temperature for Tuesday,Wednesday,Thursday and Friday was $52^{\circ}$. If the temperature on Monday was $42^{\circ}$,then the temperature on Friday was (in $degrees$):
