Answer: The first machine would cost $420
and the second machine would cost $432
you should buy the first machine
Step-by-step explanation:If you get a 30% discount, then you are paying 70% of the selling price.
Machine 1: 600(.70) = 420
Machine 2: A 10% discount means you pay 90%
600(.90) = 540 But now you get a 20% discount on that amount, which means you would pay 80%
So, 540(.80) = 432
D. 7
e. 4
f. 5
g. 11
Get these by adding/subtracting the number at the end (use the opposite operation) and then divide the coefficient from both sides.
Answer:
lol
Step-by-step explanation:
We can solve by using the substitution method
y=-5/3x+3
y=1/3x-3
They are equal to each other because they are both equal to y
-5/3x+3=1/3x-3
Subtract both sides by 1/3 and subtract 3 from both sides
-5/3x-1/3x=-3-3
-2x=-6
Divide both sides by -2
x=3
Plug in x into one of the equation to solve for y
y=1/3(3)-3
y=1-3
y=-2
