Question

Anna recorded the temperature every day for a week. It was 220C on Monday.
The temperature decreased by 20C every day. What was the average temperature for the week?

Answer 1

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

I hope it helps.
