Ill show you step by step.
This is what the equation should look like
Y=Initial value(1+/- Increasing or Decreasing value)^2 Which stands for time
So you need to do 1.0525 to the 2nd power Which equals 1.10775625
So now you need to do 15,000(1.10775625)

Which equals <span>16616 rounding to the nearest Ones
16616.3 rounding to the nearest tenth</span>

Answer:
x = $3
y = $4
Step-by-step explanation:
We need to know the prices of gravel and peas. We can find the price by using equations and graphing them.
Let X be the price of the sand
Be and the price of pea gravel
In the first purchase we have:
In the second purchase we have
Both relations represent the equation of a line. In the graphic shown, these lines are drawn. In this case the interception between both lines represents the price of each product, and the solution of the problem. You can see that the lines intersect at point (3 4). This means that the price of each bag of sand is $ 3, and the price of a bag of pea gravel is $ 4.
