PLEASE HELP! A rental car company charges $50 plus 30 cents per each mile driven.

Part1. Which of the following could be used to model the total cost of the rental where

m represents the miles driven.
A

=3m+50

B

=30m+50

C

=0.3m+50

Part 2. The total cost of driving

250 miles is;

$

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
