Answer:
After buying additional hair bands, Colleen can own a total of <em>43 hair bands.</em>
Step-by-step explanation:
Solving this problem entails of finding out the total number of hair bands Colleen can own, based on the amount she already owns and how many more she purchases. Start by reading the problem carefully to break down the information provided.
We know that Colleen already owns twenty eight hair bands. This is important to remember to include. The problem also states that she has a total of fifteen dollars and each individual hair band is priced at one dollar.
Because the hair bands are only a dollar, Colleen can purchase an additional fifteen hair bands.
Setting up an equation will help us solve. Here is how we could set up the equation:
(<em>amount of hair bands already owned </em>= 28) + (<em>number hair bands bought </em>= 15) = (<em>total number of hair bands owned </em>= x)
28 + 15 = x
The equation is now in place. Solve by adding both terms. This is how you will reach the answer.
28 + 15 = x
43 = x
This means that Colleen will have <em>43 hair bands </em>in total, after purchasing fifteen hair bands.

Answer:
The total change that will likely occur in 2 years is 
mg/L
Step-by-step explanation:
Given : The first year, they found the chloride concentration changed by 
mg/L .
It is estimated that the chloride concentration will change 
mg/L the next year.
To find : What is the total change that will likely occur in 2 years?
Solution :
The chloride concentration changed by 
mg/L in first year.
The chloride concentration will change 
mg/L the next year.
The total change that will likely occur in 2 years is
In a mixed fraction - mg/L
300,000 / 4,000 = 75
so the weight of the blue whale is 75 times bigger then the weight of the shark
