-A thermometer reading $11 ^ { \circ } \mathrm { C }$ is brought into a room with a constant temperature of $30 ^ { \circ } \mathrm { C }$ . If the thermometer reads $17 ^ { \circ } \mathrm { C }$ after 4 minutes, what will it read after being in the room for 7 minutes? Assume the cooling follows Newton's Law of Cooling:
$$\mathrm { U } = \mathrm { T } + \left( \mathrm { U } _ { \mathrm { O } } - \mathrm { T } \right) \mathrm { e } ^ { \mathrm { kt } } \text {. }$$
(Round your answer to two decimal places.)

A) $28.67 ^ { \circ } \mathrm { C }$
B) $5.87 ^ { \circ } \mathrm { C }$
C) $20.22 ^ { \circ } \mathrm { C }$
D) $39.78 ^ { \circ } \mathrm { C }$
