Answer:
South Dakota sells 12634 electric guitars p/yr.
Step-by-step explanation:
All you have to do is divide 88,438 by 7 because New York sells 7 times more. Divide that by 7 and you get 12,634
In Conclusion, your answer is that South Dakota sells 12634 electric guitars p/yr (per year) on average.
#6
Yes
Direct variation because Time increases cupcakes increases and vice versa
#B
Constant of proportionality represents the amount of time required per cupcakes
#7
Yes we can find it
We have to check the x and y values of the ordered pairs (x,y)
If y is decreasing with respect to increase in x then it's inverse variation
I believe 420 is 8.4% of 5,000. So x= 5,000.
1). Make your equation equal to 0
2). Then plug in your numbers to the quadratic equation
Answer:
Month 5 the cost will be the same
Step-by-step explanation:
Make to equations from the given information
Let y be the cost, and let x be the number of months
Club A: y = 25x + 100
Club B: y = 20x + 200
It wants to know when the cost will be the same, so set the 2 equations equal to each other and solve..
25x + 100 = 20x + 200
5x = 100 (subtract 20x and 100 from both sides)
x = 20 (divide both sides by 5)
So after 5 months the cost will be equal,
