Answer 1

The temperature on friday will be 32.5 degree celsius.

Explanation:

Given average temperature from sunday to thursday is 28 degree celsius

therefore,( S+M+T+W+TH)/5= 28

Total temperature=S+M+T+W+TH= 28*5=140 degree celsius.

as the temperature for sunday is given= 30 degree celsius

putting the value of sunday in the first equation, we get

M+T+W+TH=140-30=110 degree celsius.

Given average temperature from monday to friday= 28.5degree celsius

(M+T+W+TH+F)/5= 28.5

M+T+W+TH+F=28.5*5=142.5

therefore, friday=  142.5-110= 32.5
