Winter is coming, so Sasha decides to buy new outdoor gear. She has a coupon good for 25% off. She buys a coat with an original price of $85.75, a pair of boots with an original price of $71.99, a scarf with an original price of $24.25, and a pair of gloves with an original price of $44.95. She pays a total of $208.94. To which item did Sasha apply her coupon? A. coat b. boots C. scart d. gloves

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

the answer is the third / last answer
