Answer: (1) 1370 heart attacks per day (2) 7732 syringes and (3) 42 hrs.
Explanation:
(1) Taking 1 year=365 days.
Since in 365 days number of death due to heart attacks =1/2 millions=500,000.
So, in 1 day =500,000/365=1369.86 OR 1370 deaths per day (Rounding to a whole number).
(2) Let x number of syringes are purchaged.
So, number of defective syringes will be=3% of x i.e. x*(3/100) OR (3x/100) syringes.
So, the number of non-defective syringes will be=total number of syringes-number of defective syringes. i.e.
No. of non defective syringes=x-(3x/100)=7500
x-(3x/100)=7500
(100x-3x)/100=7500
97x=7500*100
x=(7500*100)/97
x=7731.96 OR x=7732 syringes. (rounding to a whole number).
(3) Initial fee=$100, and per hour charge=$55.
