Question

Daniela teaches Ballet. She charges a one-time processing fee of $3.00 and the cost of each class is shown below. Let x represent the number of classes and y represent the cost of classes. Based on this information, what will it cost, in dollars, to take 6 classes? (Do not put a $ in your answer.)

Cost of classes (not including processing fee) Number of Classes, x 1 2 3 4
Cost of Classes, y $16.00 $32.00 $48.00 $64.00

Answer 1

I know the answer is 89 but I dont know how to get it.

Answer 2

Okay, find the relationship between x and y.
1 class is 16 dollars, right?

Answer 3

so what's 6 x 16?
96.

Answer 4

Oh ok thank you that makes alot of sense!

Answer 5

Anytime :D

Answer 6

wait but how do you get 89?

Answer 7

It shouldn't be 89...it would actually be 99, since the three dollar processing fee.

Answer 8

but the answer is 89... I have the answer sheet and everything.... (My assignment is to fully answer all of my wrong questions and my paper says 89 is the right answer)

Answer 9

Let me look again.

Answer 10

Could it be a typo maybe? Because 6*16=96, then plus 3 for the fee, makes 99.

Answer 11

I really dont know my teacher probably isnt in right know (home schooled) so if I tried contacting her she probably wouldnt answer...

Answer 12

Well, I'm 100% sure it's 99.
Since that is the process to find the answer.
I'd send her a message anyway, just to get reassurance.

Answer 13

ok thank you could you help me with one more question? I forgot how to do the type of question

Answer 14

Okay, sure.

Answer 15

Okay
What is the value for x in the proportion x/x+10 = 7/12
There are a bunch of these and I just need to know how to do them again.

Answer 16

Okay, remember cross multiply?
