B) 23

Step-by-step explanation:

Table:            Algebra | No algebra | Total

Physics        |      4           Step 1: 8      12

No physics  |Step 2: 15

Total            |      19                              30

We look for the number of people who are in algebra and no physics or physics and no algebra.

1. 12 - 4 = 8

2. 19 - 4 = 15

3. We find the total of those numbers: 15 + 8 = 23

So at 6 pm was 72, since 6 pm was 8 less degrees than at 4 you would add 8 to 72 degrees to get 80 degrees at 4 pm. Since at 10 it was 5 degrees greater than 4 pm, which was 80 degrees, you would add 5 to 80 and get 85 degrees at 10 am. Your answer is 85 degrees.
