Answer:

Explicit formula is an = 64(-3/4)^(n-1).

Step-by-step explanation:

Looks like a geometric sequence with a negative common ratio.

-48/64 = - 3/4

36 / -48 = -3/4

Now -27/36 = -3/4 so I think there's a typo in the question. Its -27 not -17.

The required formula is 64(-3/4)^(n-1) .

Hello there,

best way to do this one is set up your story line....

4h + 8h + 50 = 164$...

let's make this easier to look at and combine like terms..

12h + 50 = 164$...

Beautiful!!! Now let's try and get the h alone?...

minus 50 to both sides...

12h = 114$..

now divide both sides by 12...

H= 9.50$/hour

Looks like you made 9.50$ an hour but Hey, at least you got that bonus ;)

If 1/6 of the bags of pet food are cat food, then the other 5/6 is other pet food.
Since there are 4 bags that make up 1/6 of the food, multiplying 4 by 6 should get the answer. 4 x 6 = 24
