Question

HELP PLEASE 50 POINTS

Answer 1

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

$c = 25 * 1 + 125$

$c = 25 + 125$

$c = 150$

When n = 2

$c = 25 * 2 + 125$

$c = 50 + 125$

$c = 175$

When n = 3

$c = 25 * 3 + 125$

$c = 75 + 125$

$c = 200$

When n = 4

$c = 25 * 4 + 125$

$c = 100 + 125$

$c = 225$

Plotting n on the x axis and c on the y axis; we have

c   ||   n

1    ||   150

2   ||   175

3   ||    200

4   ||    225

(See attachment)

From the attachment;

When she works for 3 hour; This implies that n = 3

And c = $200 when n = 3

See Proof

$c = 25n + 125$

Substitute 3 for n

$c = 25 * 3 + 125$

$c = 75 + 125$

$c = 200$
