Let matrix A represent the sales (in thousands of dollars) of a toy company in 1994 in three cities, let B represent the sales in the same cities in 1995, and let C represent the sales in the same cities in 1996. 
A = 
; B = 
; C =

Solve.If the force acting on an object stays the same, then the acceleration of the object is inversely proportional to its mass. If a force acts on an object with a mass of 30 kilograms so that it accelerates at 
per second per second, then find the acceleration of an object with a mass of 
that is acted on by the same force.
A. 45 meters per second per second B. 48 meters per second per second C. 54 meters per second per second D. 6 meters per second per second
