Answer:

The average temperature will be 160° C

Step-by-step EXPLANATION:

ACCORDING to the given information, we can write that:

at Monday the temperature was 220 C

at Tuesday , the temperature was 200 C

at Wednesday, the temperature was 180 C

at Thursday, the temperature was 160 C

at FRIDAY, the temperature was 140 C

at SATURDAY, the temperature was 120 C

at Sunday, the temperature was 100 C

Now, simply do the average, of the above:

(220 + 200 + 180 + 160 + 140 + 120 + 100)/7

= 1120/7

= 160

Therefore, the average temperature of the week is: 160 °C
