The answer should be B because 4*4=16 so 60 -16 a day
It would be: -7/12 + 7/10 = -35+42 /60 = 7/60
So, your final answer is 7/60
Hope this helps!

Answer:
B
Step-by-step explanation:
Since p and v vary inversely then the equation relating them is
p =
← k is the constant of variation
to find k use the condition p = 8 when v = 40
k = pv = 8 × 40 = 320
⇒ p(v) =
→ B
