PLS HELP ME iPhone 12 Pro Max. He earns $11.50/hour, a plus 15% commission on all iPhone
12 Pro Max’s he sells.
a. Create an algebraic equation to represent Amar’s earnings. Define all
variables.
b. What was the value of Amar’s iPhone 12 Pro Max sales if he worked for
5.5 hours and earned $854.42?

Here's link to the

cutt.ly/zxt1ipy

one that is bigger than 3 1/2

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
