Lin is shopping for a couch with her dad and hears him ask the salesperson, “How much is your commission?” The salesperson says that her commission is 5.5% of the selling price. How much commission will the salesperson earn by selling a couch for $495? a
$20, 5.5% of 495 is 20.
b
$19.08. 5.5% of 495 is 19.08.
c
$27.23, 5.5% of 495 is 27.225.

Step-by-step explanation:

The answer is $27.23 for the commission

Work out problem:

495×5.5%=27.225

So you round that off to 27.23

When working with a problem with percentages, you always multiple to figure out how you got your and what is your answer.

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
