121.3 grams of caffeine is remaining in her blood
<h3>How to determine the amount of caffeine?</h3>
The given parameters are:
- Initial, a = 175 mg
- Rate, r = 11.5%
- Time, t = 3 hours
The amount of caffeine is calculated as:
A(t) = a(1 - r)^t
This gives
A(t) = 175 * (1 - 11.5%)^t
At 3 hours, we have:
A(3) = 175 * (1 - 11.5%)^3
Evaluate
A(3) = 121.3
Hence, 121.3 grams of caffeine is remaining in her blood

Answer:
Substitute f(x)=0
0=5-4x over 15 multiply both sides
0=75-4x move the variable to the left
4x=75 divide both sides
solution x=75 over 4
alternate form is x=18 3 over 4, x=18.75
