The price of a train ticket increases from £4773 to £6443.55

Find the percentage change.

35% increase

Step-by-step explanation:

6443.55 - 4773 = 1670.55 (final value - initial value)

1670.55 / 4773 = 0.35 (divide the answer by the initial value)

0.35 * 100 = 35% (Multiply by 100 to find the percentage)

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
