  y = -2·(1/2)^x

Step-by-step explanation:

The general form of the equation can be written as ...

  y = a·b^x

where 'a' is the value of the y-intercept, and 'b' is the ratio of y-values for x-values that differ by 1.

From your table and graph, a = -2. From the table, ...

  b = -1/-2 = 1/2

Then the exponential equation is ...

  y = -2·(1/2)^x

step-by-step explanation:

well if you round, things become much more simple. round 5.95 to 6, 4.25 to 4, and 1.05 to 1. now, add 6+4+1 and that would equal 11. so the items together would equal to about $11.
