Answer:
IQR = 157.5
Step-by-step explanation:
Q1 = 518.5
Q3 = 676
Equation = 676 - 518.5 = 157.5

The mass of substance left after 7 days is 13.09 g
The mass of substance left, N is given by
N = N₀exp(-λt) where λ = decay constant and N₀ = initial mass of substance present = 24 g and t = time
Also, λ = 0.693/t' where t' = half-life of iodine = 8 days
So, λ = 0.693/t'
λ = 0.693/8
λ = 0.086625/day
Since the mass of substance left is N = N₀exp(-λt) and we require the mass of substance after t = 7 days,
N = N₀exp(-λt)
N = 24 gexp(-0.086625/day × 7 days)
N = 24 gexp(-0.606375)
N = 24 g × 0.5453
N = 13.09 g
So, the mass of substance left after 7 days is 13.09 g

To answer this item, first we subtract the $100 payment Alex made from the previous balance. That will give us an answer of $3,594.23. Then, we add the new transaction to the calculated value above giving us $3829.23. Multiplying the new transaction by 0.192 and adding the answer to $3829.23 will give us an answer of $3,874.35. Thus, the nearest answer is the third choice.
