Abby took an after-school job as a checker at Petco. She stocks 9 large bags of cat food per hour and there are already 7 large bags on the shelf when she started working. Write a function rule for the number of customers Abby has checked out after 'x' hours.

Respuesta :

Answer:

Here, x represents the number of hours and f(x) represents the number of customers has checked out.

As per the given statement:

She stocks 9 large bags of cat food per hour.

⇒Number of stock after x hours = 9x

It is also given that there are already 7 large bags on the shelf when she started working.

⇒[tex]7 + 9x[/tex]

then; a function rule is given by:

[tex]f(x) = 9x+ 7[/tex]

Therefore, a rule for the number of customers Abby has checked out after x hours is, [tex]f(x) = 9x+ 7[/tex]

Answer:

y= 9x +7

Step-by-step explanation:

What she starts with is 7 bags.  That is the y intercept  ( or 0 hours)

The rate is 9 bags per hour  ( That is the slope)

y = mx+b, where m is the slope and b is the y intercept

y is how many bad on the shelf after x hours

y= 9x +7
