In 2009, Anna paid $3,060 in federal income tax. In 2010, she paid 70% more than in 2009. How much did Anna pay in 2010?

$5,202

Step-by-step explanation:

70% more of $3,060 is 2,142.

$2,142 + $3,060 = $5,202

the answer is c

hope this !

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
