(07.07 lc)a bus pass costs $9 per week. which of the following equations shows the total cost in dollars, t, of the bus pass for a certain number of weeks, w? t = 9 + w t = 9w w = 9 + t w = 9tmy sister needs on this, and i don't remember how to solve it.

Hello,

The correct answer is B) t = 9w

Hope this helps (:

I was reading the comments from the other person who answered and I'm guessing both of you don't know what Mean Absolute Deviation (MAD) means I'm going to show you an example

For example:

2, 2, 4, 4

2 + 2 + 4 + 4 = 12 ÷ 4 = 3

12 ÷ 4 (because there are exactly 4 numbers)

Mean: 3

Mean Definition: The mean is the average of the numbers. To calculate it: add up all the numbers, then divide by how many numbers there are.

Mean Absolute Deviation (MAD):

2, 2, 4, 4          Mean: 3

(2 - 3) + (2 - 3) + (4 - 3) + (4 - 3) = 4 ÷ 4 = 1

Mean Absolute Deviation: 1

4 ( because I subtracted all the numbers and then added it all together) ÷ 4 (because there are exactly 4 number)

I hope your getting it because if you do it on paper it's easier.

Hope these helps (:
