Answer:
104 = B
Step-by-step explanation:
A quick way to do this is to use this formula
- F = 2*C + 30
- C = 40
- F = 2*40 + 30
- F = 80 + 30
- F = 110
Since this is an estimate, you are only guided to whether your answer is correct or not. Here's the actual formula
- F = (9/5) * 40 + 32
- F = 360/5 + 32
- F = 72 + 32
- F = 104
