Answer:
See Attachment for graph
Charges = $200 when number of she works for 3 hours
Step-by-step explanation:
Given
Charges = $25 per hour + $125 (c = 25n + 125)
Required
Graph the equation.
From the graph, determine c when n = 3
To plot the graph; first, we have to determine the points to use;
When n = 1
When n = 2
When n = 3
When n = 4
Plotting n on the x axis and c on the y axis; we have
c || n
1 || 150
2 || 175
3 || 200
4 || 225
<em>(See attachment)</em>
From the attachment;
When she works for 3 hour; This implies that n = 3
And c = $200 when n = 3
See Proof
Substitute 3 for n
