Barbara wants to rent a car for a trip to pine grove for a week. she phones two car rentalcompanies to get price quotes. mr cool’s rentals rents a mazda bravo for $99 for 1 weekplus $0.11 per kilometre over 100 kilometres. sensational rentals has the same vehicle for$75 per week and $0.15 per kilometre over 150 kilometres
.a)if it is 432 kilometres to pine grove and back again, which company has the better deal?

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
