To find the temperature on Sunday, let's track the temperature each day starting from Monday, using the given changes.
1. Monday:
- Temperature is \( 1^{\circ} C \).
2. Tuesday:
- On Tuesday, the temperature goes up by \( 5^{\circ} C \):
[tex]\[
1^{\circ} C + 5^{\circ} C = 6^{\circ} C
\][/tex]
- Temperature on Tuesday is \( 6^{\circ} C \).
3. Wednesday:
- On Wednesday, the temperature decreases by \( 4^{\circ} C \):
[tex]\[
6^{\circ} C - 4^{\circ} C = 2^{\circ} C
\][/tex]
- Temperature on Wednesday is \( 2^{\circ} C \).
4. Thursday:
- On Thursday, the temperature goes down by \( 7^{\circ} C \):
[tex]\[
2^{\circ} C - 7^{\circ} C = -5^{\circ} C
\][/tex]
- Temperature on Thursday is \( -5^{\circ} C \).
5. Friday:
- On Friday, the temperature increases by \( 4^{\circ} C \):
[tex]\[
-5^{\circ} C + 4^{\circ} C = -1^{\circ} C
\][/tex]
- Temperature on Friday is \( -1^{\circ} C \).
6. Saturday:
- On Saturday, the temperature decreases by \( 3^{\circ} C \):
[tex]\[
-1^{\circ} C - 3^{\circ} C = -4^{\circ} C
\][/tex]
- Temperature on Saturday is \( -4^{\circ} C \).
7. Sunday:
- On Sunday, the temperature increases by \( 8^{\circ} C \):
[tex]\[
-4^{\circ} C + 8^{\circ} C = 4^{\circ} C
\][/tex]
- Temperature on Sunday is \( 4^{\circ} C \).
Thus, the temperature on Sunday is [tex]\( 4^{\circ} C \)[/tex].
