The cost of the one word is $30 .

Option (b) i.e is used to determine the total number of words in the ad mr.grant placed.

Step-by-step explanation:

Let us assume that the number of words in the ad be x.

As given

Mr.grant spent $8.40 to place an ad in the newspaper.

This price included one time fee of $6.00 plus $0.08 per word.

Than the equation becomes

8.40 = 6 .00 + 0.08x

Simplify the above

8.4 = 6 + 0.08x

8.4 - 6 = 0.08x

x = $30

Therefore the cost of the one word is $30 .

Option (b) i.e is used to determine the total number of words in the ad mr.grant placed.
