2 answers:
Cost of 2 lemons = $ 20.50
We have to find the cost of 7 lemons. We will use unitary method to solve this problem. The unitary method is a technique which is used for solving a problem by finding the value of a single unit, i.e., 1, (by dividing) and then finding the necessary value by multiplying the single unit value.
Since, Cost of 2 lemons = $20.50
Cost of 1 lemon = $
Cost of 1 lemon = $ 10.25
Cost of 7 lemons = $
So, Cost of 7 lemons = $ 71.75
Therefore, she will pay $71.75 for 7 lemons.

Answer:
The domain represents the x-axis, more specifically, what is happening on the x-axis. So when looking at a graph, if you are asked to find the domain think about what the x-axis looks like. I put an image in to show you an example of what the domain would be for a parabola:
So on the left side of the x-axis, we can see that the line stretches out into negative infinity, so the domain would begin at negative infinity.
On the right side of the x-axis, the parabola also stretches into positive infinity, so here the domain would be (negative infinity, positive infinity), because it goes to both ends forever.
