If you follow directions and post your SCHOOL SUBJECT in the School Subject box, you're more likely to get good help.
-3° is 18° less than 15°
At 3°/hr that will take 6 hours, and happen at 6 pm.
midnight is 12 hours after noon, so the temperature then will be 15-3*12 = -21°C
Note that since 6pm is halfway between noon and midnight, since the temperature dropped 18° by 6 pm, it will drop another 18° by midnight. -3-18 = -21°
