Jacob bought a ring for $17, a necklace for $32, and a bracelet for $53. he paid $9.18 in tax for the purchase. what percent of tax did he pay?

9%

Step-by-step :

9.18 divided by 102 which is the total for everything he bought is .09 which is 9%

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

80 the answer is 80
