IrinaVladis [17]

Answer:

Option C

Step-by-step explanation:

Given the following question:

Total cost is $725
15% Marcus makes in commission.

In order to find the answer, we have to find 15% of $725 and that number will be the total in commissions he earned that week.

\frac{15\times725}{100} =15\times725=10875\div100=108.75

Marcus makes "$108.75" or option C in commissions last week.

Hope this helps.

Alex73 [517]

Answer:

The system of equations is

y=0.08x+16

y=35

Step-by-step explanation:

Let

x ----> the number of minutes of calling time

y ----> the monthly cost of the calling plan

we know that

The linear equation in slope intercept form is equal to

y=mx+b

where

m is the slope

b is the y-intercept

In this problem

Plan A

m=0.08\\b=16

substitute

y=0.08x+16 ----> equation A

Plan B

m=0\\b=35

substitute

y=35 ----> equation B

therefore

The system of equations is

y=0.08x+16

y=35

lawyer [7]

Answer: 16

Step-by-step explanation:

From the question, we are informed that there are 25 markers in a bag: 5 red, 5 yellow, 5 blue, 5 green, 5 purple and that one marker is drawn out of the bag, then put back in.

The probability of picking a blue marker will be: = 5/25 = 1/5

Therefore, the number of times that a blue marker will be expected to be picked in 80 draws would be:

= 1/5 × 80

= 16 times
