Coach Milam is organizing a going away party for one of her students. They spend $26.38 on decorations, $78.92 on food, and $34.50 on a gift. If there are 15 students in the class who agreed to split the cost evenly, then how much does each person owe?

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

"exterior angles = 360 / number of sides.

60 = 360 / sides

sides = 360 / 60

sides = 6"

im guessing (23,14). hope this : )
