I can tell you that B is NOT correct as I got it wrong.  I bet the right answer is C as it is holding steady at 1:95.

Step-by-step explanation:

These are the choices for Plato

A. The exchange rate between the U.S. dollar and the yen changes from 1:95 to 1:102.

B. The exchange rate between the U.S. dollar and the euro changes from 1:95 to 1:92. - Wrong answer

C. The exchange rate between the U.S. dollar and the euro remains 1:95

answer: d. $20

step-by-step explanation:

just took the test

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
