Answer:
C)

Explanation:
#we first write the first part of the equation.
-let the unknown number be n
-six less than the product of four = 4n-6
#We then write the second part of the number
-The opposite of a positive number is equal to negative 1 times that number.
-0.5 times the opposite of the number
=>

#we equate the two sides as:
4n-0.6<- 0.5n
