The amount of money spent at the gas station varies directly with the number of gallons purchased. When 12 gallons of gas were purchased, the cost was $39.36. How much would 9 gallons of gas cost? A. $52.48
B. $2.74
C. $30.36
D. $29.52

D

Step-by-step explanation:

$39.36 divided by 12 = $3.28

$3.28 x 9 = $29.52

she will most likely have 33  

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
