Answer:
x=3, y=-1
Step-by-step explanation:
We are already given an equation solved for x, making substitution much easier. We know x=4y+7, meaning we can put 4y+7 whenever we see x in the second equation
2x-6y=12
We substitute 4y+7 in place of x
2(4y+7)-6y=12
Now we only have one variable to work on, distribute the 2
8y+14-6y=12
Combine similar terms, 8y-6y=2y
2y+14=12
Subtract 14 from both sides
2y=-2
y=-1
Now we plug in -1 for y in the first equation to find x
x=4(-1)+7
x=-4+7
x=3
4 goes into 36 9 times and 36-36 is zero. Bring down the 2 and at a zero to it so it will be 20. Finally, 4 goes into 20 5 times. Your answer is 9.5
Not sure what answer you are looking for here so i did all of them. you’re welcome
Price = Cost / (1 – (Gross Margin/100%))
Gross Profit (Dollars) = Price x (Gross Margin/100%)
Markup = (Price / Cost) x 100%
Put it together and the
price answer is $10.71
Gross Profit $7.71
Markup 357.00%
