Y=25........x=140
y=36.........x=?
x=(36*140)/25
x=5040/25
x=201,6

Make y equal to the constant (k)multiplied by x which is. Y=KX Then put the numbers in it therefore k=0•18. Then put the new values into the y=KX 36=0•18x, X=36/0•18 therefore x=200

Answer:

B. 64.9

Step-by-step explanation:

A graphing calculator or spreadsheet can fit these points with an exponential curve. An appropriate answer for x=14 is about 73.3.

<em>Comment on the answer choices</em>

The closest answer that makes any sense is 64.9. Often these problems are worked by someone who uses inappropriate rounding of intermediate results. I haven't found the magic set of numbers to get 64.9. About the lowest I can get is 66.7, using 0.0037·e^(0.7x).
