$10.48

Step-by-step explanation:

So what you do is, you divide the cost of the masks, by how many there are, and you get a set of numbers, then you have to find the average of those numbers.

When you divide you get these numbers:

75 / 6 = 12.5

88 / 8 = 11

101 / 10 = 10.1

166 / 20 = 8.3

You then need to find the average of them, so you add all of them together and divide by 4 since there are 4 numbers.

And you get 10.475, you round up since you can't have half of a penny.

answer:   n ≤ -3 or n < -5

step-by-step explanation:

-5 + 2n ≥ -11

+5             +5

2n ≥ -6

2/2 ≤ -6/2

n ≤ -3

-6 - 10n > 44

+6           +6

-10n > 50

-10/-10 50/-10

n < -5
