Answer:
After 4 days, the temperature will be 3/4 Fahrenheit degrees lower than today
Explanation:
Let's calculate the change in temperature after 4 days, this way:
Today's temperature = t in Fahrenheit degrees
Tomorrow's temperature = t - 3/16 Fahrenheit degrees
The day after tomorrow's temperature = t - 2 * 3/16 = t - 3/8 Fahrenheit degrees
Therefore, the temperature after 4 days will be = t - 4 * - 3/16 = t - 3/4 Fahrenheit degrees
After 4 days, the temperature will be 3/4 Fahrenheit degrees lower than today
