Writing an inequality
In order to write an inequality we can read the original statement in small parts.
In this case, the statement is:
"the product of c and 9 is greater than 16"
We have that "the product" is a multiplication
Then, "the product of c and 9" is the multiplication between c and 9:
9 · c
And, "the product of c and 9 is greater than 16" means that 9 · c is greater than 16:
9 · c > 16
Answer: 9 · c > 16
