Answer:
a) 1133.98 ≈ 1134 packs
b) 125 packs
Step-by-step explanation:
Given:
Tar present in 1 cigarette = 5 mg
Nicotine present in 1 cigarette = 0.4 mg
Number of cigarettes in 1 pack = 20
thus,
Tar present in 1 pack of cigarette = 5 × 20 = 100 mg
Nicotine present in 1 pack of cigarette = 0.4 × 20 = 8 mg
now,
1 oz = 28349.5 mg
thus,
for 4 oz = 4 × 28349.5 mg = 113398 mg
Therefore,
Number of packs required for 4 oz ( 113398 mg ) tar
= 
= 1133.98 packs ≈ 1134
also,
Number of packs required for 1 g (1000 mg) nicotine
= 
= 125 packs
N represents the number of payment periods. Supposing you arranged for a mortgage to buy a house; you'd have to make n payments of so many dollars per month to pay off the mortgage (the total amount due,with interest).
If the annual interest rate were r, and payments were due monthly (12 payments per year), then the monthly interest rate would be r/n = r/12. The typical 30-year mortgage involves monthly payments over a 30 year time span. This comes to 360 monthly mortgage payments.
