Issac is a clothing salesman working on straight commission. He sold $1311 this week and gets 9% commission. How much did he earn?

Isaac earned $117.99 this week

Step-by-step explanation:

Percentages

The N% of a quantity M is calculated as follows:

N * M / 100

Isaac earns a 9% commission for his sales.

This week he sold $1,311, thus his commission is:

9 * 1,311 / 100 = 117.99

Isaac earned $117.99 this week

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
