QveST [7]

Answer:

The consultant's possible daily profit is $232, given that the work expenses ($8) is a daily thing and not an hourly thing.

Step-by-step explanation:

To construct a graph, you first need to figure out the possible daily income. Given that the consultant makes $30 an hour and works 8 hours a day, they make $240 from work. However, they lose $8 of that due to work-related expenses, so in total, they make $232 a day. Now time to construct a graph.

For the x-axis, you want to put the number of days worked (1, 2, 3, 4, 5). For the y-axis, you want to put the profits ($232, $464, $696, $928 and $1160). Place dots at (1, 232), (2, 464), (3, 696), (4,928) and (5,1160), and draw a line through. It will show the daily profit as $232.

6x = 9

divide by 6

x = 9/6 = 3/2

x = 3/2
