The dolphin daily charges by word to run an ad in their paper. the newspaper charges $5 for the first 20 words and $0.25 for each additional word. evenson wants to run a 31 word ad. how much will this cost him?

31 word ad will cost $7.75 to Evenson.

Step-by-step explanation:

The charge for first 20 words = $5

The next each word costs =   $0.25 each word

Total number of words need to be published by Evenson = 31

Now, 31  =  20 + 11

Now, cost of first 20 words  = $5

and Cost of additional 11 words  = 11 x (Price of each additional word)

                                                        = 11 x ($0.25)  = $2.75

or the additional 11 words costs = $2.75

Now,  Total cost  = Fixed price of 20 words + additional cost of 11 words

                           = $5  +  $2.75

                          = $7.75

or, Total cost of 31 word ad  = $7.75

Hence, a 31 word ad will cost $7.75 to Evenson.
