Step-by-step explanation:
we need to find the number n of sold boxes, so that the income (sales) and costs (expenditures) are equal. this is called the break even point. any more boxes sold will then result in a profit, actually gaining money. and if she cannot reach that number of sold boxes, then she will make a loss.
so,
n×11 = n×3 + 24
n×8 = 24
n = 3
it will take 3 sold boxes of cards to break even.
at that point she will have spent $24 + 3×$3 = $33, and her sales will be 3×$11 = $33.
Assuming you meant 6x198 do a mental sum for 6x200 (1200) then subtract 6x2(12)to give you 1188
Answer:
Closed-end credit is a type of credit that should be repaid in full amount by the end of the term, by a specified date. The repayment includes all the interests and financial charges agreed at the signing of the credit agreement. Closed-end credits include all kinds of mortgage lending and car loans.

The equation of line passing through the points (3,3) and (-3,5) is:
x+3y=12
Step-by-step explanation:
Given points are:
(x1, y1) = (3,3)
(x2, y2) = (-3, 5)
The general form of slope-intercept form is:
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
We have to find slope first
![m=\frac{y_2-y_1}{x_2-x_1}\\=\frac{5-3}{-3-3}\\=\frac{2}{-6}\\=-\frac{1}{3}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%5C%5C%3D%5Cfrac%7B5-3%7D%7B-3-3%7D%5C%5C%3D%5Cfrac%7B2%7D%7B-6%7D%5C%5C%3D-%5Cfrac%7B1%7D%7B3%7D)
Putting the value of m in general form
![y=-\frac{1}{3}x+b](https://tex.z-dn.net/?f=y%3D-%5Cfrac%7B1%7D%7B3%7Dx%2Bb)
To find the value of b, putting (3,3) in equation
![3=-\frac{1}{3}(3)+b\\3=-1+b\\b=4](https://tex.z-dn.net/?f=3%3D-%5Cfrac%7B1%7D%7B3%7D%283%29%2Bb%5C%5C3%3D-1%2Bb%5C%5Cb%3D4)
Putting the values of m and b in general form
![y=-\frac{1}{3}x+4](https://tex.z-dn.net/?f=y%3D-%5Cfrac%7B1%7D%7B3%7Dx%2B4)
Multiplying both sides by 3
![3y=-x+12\\x+3y=12](https://tex.z-dn.net/?f=3y%3D-x%2B12%5C%5Cx%2B3y%3D12)
The equation of line passing through the points (3,3) and (-3,5) is:
x+3y=12

Answer:
first you need to set up the equation which is 20+2x=44 then isolate 2x by doing the inverse operation for 20 which is -20 and add them to both sides which would now give you 2x=24 so divde 24 by 2 which is 12, x=12 answer 12ml
