Mindy earns income equal to 40% of her sales minus the shipping cost of her products. She wants her income to be at least $1,500 this month and calculates that her total shipping cost will be $48. This can be represented by the inequality 0.4

x = -2

y = 848

step-by-step explanation:

plug in the numbers

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
