The question is posed INCORRECTLY.

It should ask about COST of work --- not about the rates, that are given.

Company A+
Flat rate of $3 plus 7 cents per word.
f%28x%29=7x%2B3
Company B
Flat rate of $1.50 plus 12 cents per word.
f%28x%29=12x%2B1.50

If an advertisement contains x number of words, for what values of x is Company A’s rates cheaper than Company B?
yes, Company A’s rates cheaper than Company B: price per word= 7 is less than price per word=12

check:
Company A : if number of words is x=10,x=30,
f%28x%29=7%2A10%2B3=73
f%28x%29=7%2A30%2B3=213
Company B:if x=10,x=30
f%28x%29=12%2A10%2B1.50=121.50
f%28x%29=12%2A30%2B1.50=361.50

The CORRECT inequality you're looking for is: .07x + 3 < .12x + 1.5
When solved, you should get x > 30, and so, highlight_green%28matrix%281%2C4%2C+more%2C+than%2C+30%2C+words%29%29 will result in Company A's cost being lower than Company B's!
