Well, here is how i would do it.
We start with 225, at a rate of 15% per year. Assuming your answers are in years and not months, we will increase by this increment; years.
So, we start with 225, and a 15%, or .15, increase. So what we would do, it take 225 times .15. One way ive learned to do this (via algebra class) is that you can times it by 1.15 to make it quicker, this just takes out the adding step.
So after one year, we would have a total of 258.75, or about 259 wolves.
after two years, we would have about 298 (we cant have a half of a wolf!)
after 3 years, we would have about 343 wolves.
after 4 years, we would have about 394 ish
after 5 years, we would have about 453
after 6 years, we would have about 521.
So, it would take about 5 and a half years, if thats an option choice.
Answer:
No, she couldn't have scored only two goals because that would mean Kenny scored six and 2 + 6 does not equal 12.
Step-by-step explanation:
Let x = Number of goals Carrie scored
Let 3x = Number of goals Kenny scored (three times Carrie)
Now we set up an equation showing that they both scored a sum of 12 goals.
3x + x = 12
Combine like terms
4x = 12
Divide both sides by 4 to isolate variable x
x = 12/4
x = 3
Carrie scored 3 goals. So your answer is no.
By the way your question was asked, the unit rate would be one foot per inch, or a 1ft:1in ratio.
Answer:
Hourly rate: $17.
Hourly overtime rate: $25.5.
Step-by-step explanation:
Let x represent Jim's hourly pay.
We have been given that Jim worked 40 hours last week. So amount paid in 40 hours would be 
.
We are also told that his over time pay is time-and-a-half rate that is 
.
The amount earned for working 8 overtime hours would be 
.
Since Jim's gross pay was $884, so we will equate amount earned in 40 hours and 8 hours of overtime with 884 as:
Therefore, Jim's hourly rate is $17.
Overtime rate would be 
Therefore, Jim's hourly overtime rate is $25.5.
