Answer:
y=2500(0.85)^d
Step-by-step explanation:
Seeing as there are no option choices, I shall digress.
Because of a decrease of 15% each day, it means exponential decay. Using the formula y=a(1-r)^x, we have y=2500(1-0.15)^d -> y=2500(0.85)^d
Your function would thus be y=2500(0.85)^d
Answer:
The function that can be used is x = (2500 × 0.15)(number of days, or d)
Step-by-step explanation:
First we can create an equation to find this easier. We can say that x, or the number of infected students, is equal to (2500 × 0.15), since percentages are easily changed into decimals, and multiply that by the number of days or d.
