Answer:

B. Barbara’s equation did not consider the number of iced tea drinks.

Step-by-step explanation:

Barbara sells iced tea for a $1.49 per bottle and water for $1.25 per bottle.

She wrote a equation to find the number of drinks she needs to sell to earn $100.

1.25x+1.49=100 ; here x is the number of water bottles sold.

She forgot to write a variable with 1.49 like :

1.25x+1.49y=100

Therefore, the answer is : Barbara’s equation did not consider the number of iced tea drinks.

The Bayside Bugle charges by the word to run automotive ads. The newspaper
11111nata11111 [884]

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
