<h3>
Answer: 1227.50 dollars</h3>
======================================================
Explanation:
The simple interest formula to use is
A = P*(1+r*t)
where,
A = account value after t years (original deposit + interest)
P = 1000 = amount deposited (principal)
r = 0.0325 = annual interest rate in decimal form
t = 7 = number of years
So,
A = P*(1+r*t)
A = 1000*(1+0.0325*7)
A = 1227.50
Side note: you've earned A-P = 1227.50-1000 = 277.50 dollars in total interest

Answer:
∴35.97 mg caffeine would be left in the system after 5 hours.
Step-by-step explanation:
Given that,
A cup of coffee has approximately 310 mg of caffeine.
Caffeine decrease at a rate 35% per hour.
Exponential Function:
y(t)= Amount caffeine after t hours
= Initial amount of caffeine
r= rate of decrease
t = Time in hour.
Here y(t)=?, = 310 mg, r=35%=0.35, t= 5 hours
=35.97 mg
∴35.97 mg caffeine would be left in the system after 5 hours.
