Answer:
$20.45
Step-by-step explanation:
Since the Bayside Bugle charges $18 for the first 20 words and there is more than 20 words in the ad you take 27-20 and you get 7 additional words.
Now we know that we already have to pay $18 for the first $20 words.
Since we have 7 additional words we multiply that by 0.35 cents and you get $2.45.
Next we add up our two numbers (2.45+18) we get the total of $20.45 fro a 27-word ad.
I hope this helps :)
Answer: Part a) 375 pounds, Part b) 8 words
Step-by-step explanation:
a)
<u />
Since n represents the number of words there are, we can plug in 20 for n into the equation to get:
C = 15*20 + 75 pounds
C = 300 + 75 pounds
C = 375 pounds
b)
Since C represents the cost of the advert, we can plug in 195 for C into the equation to get:
195 = 15n + 75
Subtract 75 from both sides:
120 = 15n
Divide both sides by 15:
n = 8 words
