Answer:
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.
