solniwko [45]

Answer:

Minimum temperature is 68.5 ° and maximum temperature is 76.5 °

Step-by-step explanation:

|x - 72.5| = 4\\it\  can \ be \ written \ as \\72.5-x=4\\-x=4-72.5\\x=68.5

When the Temperature of x is maximum So the Maximum Temperature is

|x -72.5| = 4\\x-72.5=\ 4\\x=72.5+4\\x=76.5

Therefore The minimum temperature is 68.5 ° and the maximum temperature is 76.5 °
