Answer:
2nd option ,that is, Both tables do not represent a function.
Step-by-step explanation:
For a table to represent a function it's input value must correspond to exactly one output value.
As in Table A the input value of 3 corresponds to 2 different outputs, where
as in table B the input value of 5 corresponds to 2 different outputs.
- x is taken as the input and y is taken as output for both the tables.
Therefore, Both tables dobnot represent a function.

Answer:
The answer is below
Step-by-step explanation:
Let x represent the number of single cone ice cream and let y represent the number of double cone ice cream.
Since the vendor stocks a maximum of 70 single cones and a maximum of 45 double cones. hence:
0 < x ≤ 70, 0 < y ≤ 45 (1)
The vendor expects to sell no more than 50 ice creams, hence:
x + y ≤ 50
Plotting the constraint using geogebra online graphing tool, we can see that the solution to the problem is at (5, 45)
Since the vendor sells single-cone ice-creams for $3 and double-cone ice-creams for $4.50, hence:
Revenue = 3x + 4.5y
At the point (5, 45), the revenue is:
Revenue = 3(5) + 4.5(45) = $217.5
