I think it's D but not sure
Answer:
$ 530.5
Step-by-step explanation:
Income = $415 + Commission
Sonia made sales of $2,200. This means she will earn 5.25% of 2,200 as commission.
5.25% of 2200= 0.0525 x 2200 = 5.25 x 22 = $ 115.5
Therefore, total income of Sonia would be:
Total income = $ 415+ $ 115.5 = $ 530.5
The tax is 11.90 so the total is 218.78
Answer:
2
Step-by-step explanation:
The first graph does not represent the linear relationship, because the slope of the line connecting points (3,60) and (4,90) is

and the slope of the line connecting points (4,90) and (5,110) is

Since slopes differe, this is not linear relationship. Simply, if you connect all points on the graph, they will not lie on the same line.
Two next graphs represent the linear relationships, so they represent the llinear relationship.
A. 2.8x+3
B. -73/156
C. 6 10/21+ 10 6/7
D is already simplified
