Question

At 2:30 am the temperature in Joelle is 3 F. The temperature drops 3/4 of a degree in 30 min. What is the temperature on Joelle at 3:00am?

Answer 1

The answer is B. 2.25 degrees Fahrenheit because if you subtract 3/4 from 3, you shall get 2.25.

Answer 2

Answer:  B. $=2.25^{\circ}F$

Step-by-step explanation:

Given: At 2:30 am the temperature in Joelle is 3 F.

The temperature drops 3/4 of a degree in 30 min.

3/4 of a degree= $\frac{3}{4}\times1^{\circ}F=\frac{3}{4}=0.75^{\circ}F$

Therefore, the temperature on Joelle after 30 min= $3^{\circ}F-\frac{3}{4}\ of\ 1^{\circ}F$

$=3^{\circ}F-0.75^{\circ}F$

$=2.25^{\circ}F$

Thus, the temperature on Joelle at 3:00am=$=2.25^{\circ}F$
