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: x = 41.22 and 38.78
Step-by-step explanation:
Given the equation
4x² - 40x + 94 = 0
Using the general formula
x = -b+/-√b²-4ac/2a
Where a = 4, b= -40 c= 94
x = -(-40)+/-√(-40)²-4(4)(94)/2(4)
x = 40+/-√1600-1504/8
x = 40 +/-√96/8
x = 40 +/-9.8/8
x = 40+/-1.22
x= 40+2.22 = 41.22
and x = 40 -1.22
x = 38.78
The order from least to greatest is bike, family vehicle, school bus.
This answer is 135.
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
$2.40/34= 0.070588235294118 is the answer I believe
