you're absolutely correct.
each system is sold for $2150, that includes cost + markup, namely the markup is the surplus amount otherwise called "profit".
they sold 12 of those, 2150 * 12 = 25800
they had $4824.36 in profits from it, so if we subtract that from the sale price, we'll be left with the cost of all 12 systems
25800 - 4824.36 = 20975.64
that's the cost for all 12 systems sold, how many times does 12 go into 20975.64? 20975.64 ÷ 12 = 1747.97.
Answer:
x = 0.1, y = 0.075
Step-by-step explanation:
Given the 2 equations
27x + 24y = 4.5 → (1)
1.5x + y = 0.225 → (2)
Multiplying (2) by - 24 and adding to (1) will eliminate the y- term
- 36x - 24y = - 5.4 → (3)
Add (1) and (3) term by term to eliminate y
- 9x = - 0.9 ( divide both sides by - 9 )
x = 0.1
Substitute x = 0.1 into either of the 2 equations and solve for y
Substituting into (2)
1.5(0.1) + y = 0.225
0.15 + y = 0.225 ( subtract 0.15 from both sides )
y = 0.075
1000+9 x 100 + 9 x 10 + 3 x 1 or 1000 + 900+ 90 + 3
Answer:
2/4? i think....
idrk sry :(
Step-by-step explanation:
x-intercept is (2,0)
y-intercept is (0,-5)
Step-by-step explanation:
Danielle plans to graph the linear equation 5x-2y=10 by plotting the x-intercept and y-intercept.
Finding x-intercept
X-intercept: Substitute 0 for y and then solve for x. Write your answer in the form (__, 0)
Putting y=0
So, x-intercept is (2,0)
Finding y-intercept
Y-intercept: Substitute 0 for x and then solve for y. Write your answer in the form (0, __)
Putting x=0
So, y-intercept is (0,-5)
