color : 40p + 50f + 90
b&w : 15p+20f + 45
p = 26
f = 45
[substitute the values given]
color : 40(26) + 50(45) + 90
b&w : 15(26)+20(45) + 45
[solve the equation]
color : 3380
b&w : 1335
[subtract to see how much ink is saved]
3380 - 1335 = <u>2045</u>

Answer:
$323
Step-by-step explanation:
Hello! First you would need to divide $171 by 9 to see how much money she makes an hour....
$171 / 9 = $19 an hour
Now that you know how much she makes an hour, multiply that amount by 17 to find out how much money she will make if she works for 17 hours.
$19 * 17 = $323
She will make $323 if she works for 17 hrs. :)
Hope this helps!

Answer:
8/10
Step-by-step explanation:
8/10 = 80/100 > 63/100
A.) Probability of selecting two students and two faculty members from 20 students and 5 faculty volunteers = no of ways of selecting two students and two faculty members from 20 students and 5 faculty volunteers divided by the number of ways of selecting 4 people from 25 people = (20C2 x 5C2) / 25C5 = 1900 / 53130 = 0.036 = 3.58%
b.) Probability of selecting three students and one faculty members from 20
students and 5 faculty volunteers = no of ways of selecting three students
and one faculty members from 20 students and 5 faculty volunteers
divided by the number of ways of selecting 4 people from 25 people = (20C3 x 5C1) / 25C5 = 5700 / 53130 = 0.107 = 10.7%
