The temperature on Monday was 14°C. On Tuesday the temperature decreased by 5°. On Wednesday the temperature decreased another 10°. On Tuesday the temperature increased by 8°. What was the temperature at the end of the day on Thursday.
Let's start with the initial temperature on Monday, which was 14°C.
On Tuesday, the temperature decreased by 5°C. So, 14°C - 5°C = 9°C.
On Wednesday, the temperature decreased another 10°C. So, 9°C - 10°C = -1°C.
On Thursday, the temperature increased by 8°C. So, -1°C + 8°C = 7°C.
Therefore, the temperature at the end of the day on Thursday was 7°C.
To find the temperature at the end of the day on Thursday, we need to start with the temperature on Monday and then follow the given changes day by day.
Given:
Temperature on Monday = 14°C
Temperature decreased by 5°C on Tuesday
Temperature decreased by another 10°C on Wednesday
Temperature increased by 8°C on Thursday
Step-by-step calculation:
1. Start with the temperature on Monday: 14°C
2. On Tuesday, the temperature decreased by 5°C. So, subtract 5 from the temperature on Monday:
Temperature on Tuesday = 14°C - 5°C = 9°C
3. On Wednesday, the temperature decreased by another 10°C. So, subtract 10 from the temperature on Tuesday:
Temperature on Wednesday = 9°C - 10°C = -1°C
4. On Thursday, the temperature increased by 8°C. So, add 8 to the temperature on Wednesday:
Temperature on Thursday = -1°C + 8°C = 7°C
Therefore, the temperature at the end of the day on Thursday was 7°C.
