Julia owns a coffee shop. She experimented with mixing City Roast Colombian coffee that costs $7.80 per pound with French Roast
2 answers:
Answer: They should buy 12 pounds of City Roast and 8 pounds of French Roast.
Step-by-step explanation:
Let x be the weight of City Roast colombian coffee.
Let y be the weight of French Roast Colombian coffee.
Weight of blend = 20 pounds
So, our equation becomes
Cost of per pound of City Roast = $7.80
Cost of per pound of French Roast = $8.10
Cost of blend = $7.92
So, our equation becomes,
From Eq(1), we get that
Put this in Eq(2), we get that
Hence, they should buy 12 pounds of City Roast and 8 pounds of French Roast.

For 1 and 2, you plot both lines, and wherever they intersect is the solution to the system. Given the equation of a line, I think the easiest way to plot it is to find two points on the line, then draw a line through them. For example, if , then when
, you get
; when
, you get
. So plot the points (0, -1) and (1, 4), then strike a line through.
1. Notice that dividing both sides of by 2 returns
, same as the first equation. So the system of equations reduces to one equation, which can have an infinite number of solutions. (This is because for any choice of
or
, you can always find a corresponding value for the other variable.)
2. See attached image. is given by the purple line.
For 3-6, you have several options. The two simplest methods of solving them are by substitution or elimination.
3. Like with (1), notice that dividing both sides of the first equation by 2 gives , so there will be an infinite number of solutions.
4. (by substitution) Since , we can replace
in the second equation:
but this is false, so there are no solutions to this system.
5. (by substitution) Since , in the first equation we have
Then back in the second equation we find
So (-4, -3) is the only solution here.
6. (by substitution) Notice that the left hand sides of both equations are the same, so we end up with 7 = 12, but this is false, so no solution exists.
