The temperature drops 28°. After the drop, the thermometer reads 48°. Which integer represents the number of degrees the temperature drops?

A)
−28°

B)
−20°

C)
28°

D)
48°

-28° represents the number of degrees the temperature drops . Correct option A) -28° .

Step-by-step explanation:

Here we have , The temperature drops 28°. After the drop, the thermometer reads 48°. Let us suppose that initially the temperature was x , and after drop it's 48 i.e.

x - (28) = 48

We are supposed to tell that how from how many temperatures drop is there , which is -28° where 28 tells us about the value or number that temperature is dropped & - ( minus) sign indicates that there is fall or drop in temperature . So , drop in temperature is given by  -28° .

Hence , -28° represents the number of degrees the temperature drops . Correct option A)-28° .
