Solution:
Step 1:
We will calculate the volume of ice cream in the single scoop
The volume of the ice cream will be

By substituting the values, we will have

Step 2:
We will use the formula below to calculate the volume of the two scoops of ic cream

Step 3:
We will use the formula below to calculate the volume of the three scoops of ic cream

For the first ice cream with one scoop

For the second ice cream with two scoops

For the third ice cream with three scoops

Hence,
The final answer is
The triple sold at $5.50 has the best value because it has the lowest price of $0.21 per cubic inch of the ice cream
The answer to your problem is 2
Problem 7)
The answer is choice B. Only graph 2 contains an Euler circuit.
-----------------
To have a Euler circuit, each vertex must have an even number of paths connecting to it. This does not happen with graph 1 since vertex A and vertex D have an odd number of vertices (3 each). The odd vertex count makes it impossible to travel back to the starting point, while making sure to only use each edge one time only.
With graph 2, each vertex has exactly two edges attached to it. So an Euler circuit is possible here.

Work Shown:
abc base 2 = (a*2^2 + b*2^1 + c*2^0) base 10
101 base 2 = (1*2^2 + 0*2^1 + 1*2^0) base 10
101 base 2 = (1*4 + 0*2 + 1*1) base 10
101 base 2 = (4 + 0 + 1) base 10
101 base 2 = 5 base 10
B. Step 1. 14x - 6 = 9
Step 2. 14x = 15
Let's calculate the slope of the A(3,1.5) and B(5, 2.5)
The formula of the slope m =(y₂-y₁)/(x₂-x₁)
m = (2.5 - 1.5)/(5 - 3)
m = (1)/(2) = 0.5
