Question

The average of the Saturday & Sunday was 82oF; the average of the Sunday
& Monday was 85oF. If the temperature of the Monday was 89oF what was the
temperature on Saturday

Answer 1

Answer:

Suppose Temperature of Sunday = S

And Temperature of Saturday = x

Now,

Sunday + Monday / 2 = 85

and Monday = 89

therefore S + 89 / 2 = 85

S + 89 = 170

S = 170-89

S = 81°

Now,

S + x / 2 = 82

therefore 81 + x = 164

Therefore x = 164-81

Therefore temperature of saturday is 83°
