Your answer would be 15.6
Answer:
B. The company hires 10 employees every year.
Step-by-step explanation:
One way to look at this is to look at the units on the number 10. Working strictly with units, we get ...
f(x) = 10x . . . . . . f(x) is employees, x is years
employees = 10·years
Dividing by years, we find the meaning of "10":
employees/year = 10
The division symbol (/) is read as "per", so this means the number 10 in the equation is the number of employees per year that are hired.
10 employees are hired every year.
207 divide 31 = 6.7 miles per day
y= days
x= distance
y=6.7
