Emma has $3.15 worth of dimes and quarters. she has twice as many dimes as quarters. determine the number of dimes and the number of quarters that emma has.

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

he sells x mount because thats eqivilqant to the maz and then divided into quarters
