The temperature at noon is 75 degreesF. The temperature drops 3 degrees every half hour. What is the temperature at 4.pm.

I'm studying Multiplying Rational numbers and I don't know how to set this up.

noon to four = 4 hours

4 * 2 = 8

3 * 8 = 24 degrees

75 - 24 = ?

2. Kaydence

51

3. Peanut butter

The answer is 51

4. this is not a answer

where did you get the two

5. Tommy

51

3 degrees every half hour (so it drops 6 degrees in an hour).
4 hours total

75-(3×2/1×4)=51
