The fees for two companies is shown below: company A: Flat rate of $3 plus 7 cents per word. Company B: Flat rate of $1.50 plus 12 cents per word. If an advertisement contains x number of words, for what values of x is company A's rates cheaper than company B's?
Correct ''A'' is cheaper than ''B'' because flat rate of 3 plus 7 cent per word meaning ''B'' flat rate of 1.50 plus 12 and uu would rather pay 1.20 than 1.50
