Answer: There are 120 boats in the marina.
Step-by-step explanation:
Let's suppose that there are N boats
We know that 5/6 of them are white, then we have: (5/6)*N white boats.
The remaining is: N - (5/6)*N = (1/6)*N
We know that 2/5 of the remaining are blue, then we have:
(2/5)*(1/6)*N blue boats
And the rest are red, the rest is:
(1/6)*N - (2/5)*(1/6)*N = (3/5)*(1/6)*N
Then we have (3/5)*(1/6)*N red boats.
And we know that there are 12 red boats, then:
(3/5)*(1/6)*N = 12
Now we can solve this for N, which is the total number of boats in the marina.
N = 12*(6)*(5/3) = 120
There are 120 boats in the marina.
Answer:

CHECK THE COMPLETE QUESTION
Lin is shopping for a couch with her dad and heard him ask the salesperson “how much is your commission?” The salesperson says that her commission is 5 1/2% of the selling price. A.How much commission will the salesperson earn by selling a couch for $495?
B.How much money will the store get from the sale of the couch?
From the question, the commission of the salesperson is 5 1/2 % , we can convert to improper fraction as 11/5%, then we can convert to decimal by dividing the numerator by denominator which is 5.5% , we can convert from percentage by saying(5.5%/100)
= 0.055
A)How much commission will the salesperson earn by selling a couch for $495?
His Commission will be
(0.055 x $495 )
= $27.23
B.How much money will the store get from the sale of the couch?
Since we know this Commission as $27.23, then the amount the store get from sale will be
(difference between the commission and the selling price)
($495.00- $27.23)
= $467.77
Answer:
New price is $11.02
Step-by-step explanation:
<u>Step 1: Find the new price</u>
<u>Step 2: Multiply</u>
Answer: New price is $11.02
Compare 100 to 110, and see that to go from 100 to 110 is a 10% increase, but to go from 110 back down to 100 is a 9.09% decrease not a 10% decrease
