Determine if the statement is true or false: a. If two matrices are equivalent, then one can be transformed into the other with a sequence of elementary row operations.
b. Different sequences of row operations can lead to different echelon forms for the same matrix.
c. Different sequences of row operations can lead to different reduced echelon forms for the same matrix.
d. If a linear system has four equations and seven variables, then it must have infinitely many solutions.

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5

c > -10.55

step-by-step explanation:

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100
