Question

The temperature is changing every day by negative 3 over 16 degrees Fahrenheit. What will be the change in the temperature after 4 days?

negative 64 over 3 degrees Fahrenheit

negative 3 over 4 degrees Fahrenheit

3 over 64 degrees Fahrenheit

3 over 4 degrees Fahrenheit

Answer 1

Option B.

Explanation:

It is given that the temperature is changing every day by negative 3 over 16 degrees Fahrenheit.

Change in the temperature after one day =
`(-(3)/(16))^(\circ)Fahrenheit`

Change in the temperature after four days is 4 times of change in the temperature after one day.

Change in the temperature after four days =
`4* (-(3)/(16))^(\circ)Fahrenheit`

Cancel out common factors.

Change in the temperature after four days =
`(-(3)/(4))^(\circ)Fahrenheit`

The change in the temperature after 4 days will be negative 3 over 4 degrees Fahrenheit.

Therefore, the correct option is B.

Answer 2

`-(3)/(4)` degrees Fahrenheit

Explanation:

• Everyday temperature is changing
  `-(3)/(16)` degrees.

• So, in 4 days, it is going to change
  `4(-(3)/(16))=-(12)/(16)=-(3)/(4)` degrees.

Second answer choice is correct.
