12,500 / 100 = 125 125 x 4.5 = 562.5 562.5 x 4 = 2250
2250 + 12,500 = 14,750 He paid back a total of $14,750. Hope this helps :)
Answer:
260 assignments in a school year
Step by Step:
There are 180 days in a school year and you do 3 assignments per day you multiple 180 and 3
I would say take 2 from eight which equals 6
The function represents the number of accidents (f(x)) per 50 million miles driven as a function of the driver's age (x).

f(45) indicates that you have to find the value of f(x) when x=45, to do so replace the equation of the function with the value of x and solve for f(x)

For x=45 years f(x)=190
f(45)=190; This value indicates that 45-year-old drivers had 190 accidents per 50 million miles driven.
