Piper signed up for a streaming music service where there's a fixed cost for monthly membership and a cost per song downloaded. Her total cost per month is given by
the equation c =
0.5x + 2.99, where x represents the number of songs she
downloads and c represents the total cost, in dollars and cents. What could the
number 0.5 represent in the equation?

yor answer is 7/6 times 5

step-by-step explanation:

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
