The function models the number of accidents

f(60)=280

Step-by-step explanation:

f(x)=0.4x²-36x+1,000

x=60→f(60)=0.4(60)²-36(60)+1,000

f(60)=0.4(3,600)-2,160+1,000

f(60)=1,440-2,160+1,000

f(60)=280

This mean that a driver of 60 years old will have 280 accidents per 50 million miles driven.

2,600 divided by 80 = 32.5

step-by-step explanation:

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.
