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`

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=
`(3)/(4)*1^(\circ)F=(3)/(4)=0.75^(\circ)F`

Therefore, the temperature on Joelle after 30 min=
`3^(\circ)F-(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`
