Answer:
27
Step-by-step explanation:
x + y = 30
0.05x + 0.15y = 1.80
x = 30 - y
1.5 - 0.05y + 0.15y = 1.80
0.10y = 0.30
y = 3 (bottles)
x = 27 (cans)
Answer:

Step-by-step explanation:
So the point-slope formula looks like this: 
= any y point on the line
= any x point on the line
= the slope
And hey, look, we're already given all that information!
So we can just plug those values into the equation:

(*note: It's a +3.2 because 3.2 was negative in the first place, and -(-x) = +x)
