A car was valued at $37,000 in the year 2009. By 2013, the car value had depreciated to $14,000. If the car's value continues to drop by the same percentage, what will it be worth in 2020? Round to the nearest dollar.

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

the answer is c)8
