Last weekend you attended a concert. You spent a total of $180. Twenty percent of the cost was for a parking pass. The rest of the money was used on 5 tickets. How much was each ticket?

The cost of each ticket was $28.80

Step-by-step explanation:

20% of $180 is $36. 180-36=144. Since there were 5 tickets, the total would be $28.80 for each ticket, which was $144 in all.

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

20
