Answer:
B
Step-by-step explanation:
you can use foil and the graph,
because you can see (in the graph) that the lines intersect at 1 and 4.
just use foil to help figure out which matches the slope.
something else (the normal way) is find which 2 numbers equal to the last coefficient, in this case it can be
-2 and -2, 2 and 2, 4 and 1 or -4 and -1, multiply them and if they make up the last coefficient, and added it equals the second coefficient it is correct.
Well This is how you get a square to get the eligble answer so there.
<span>Let p be the purchase
price, and c be the change.
Expression: $20.00 - p = c
Table (you'll have to imagine it as a table)</span>

When p is | Then C is
11.59 | 8.41
17.50 | 2.50
19.00 | 1.00
20.00 | 0.00</span>
