a. The total cost is the sum of variable and fixed cost.
So the average cost of each hat is simply total cost divided by x:
ave cost = (2.12 x + 3000) / x
b. Total cost should be equal to Income:
2.12 x + 3000 = 2.75 x
Solve for x:
x = 4762 units
c. Profit is income minus total cost:
Profit = 2.75 x – (2.12 x + 3000)
1000 = 2.75x – 2.12 x – 3000
Solving for x:
<span>x = 6439 hats</span>
In that 16 minutes, the amount that leaks out is (8 - 6) = 2 gallons.
The average unit rate of the leak is
(2 gal)/(16 min) = (2/16) (gal/min) = 1/8 gal/min
= 16 fluid ounce per min
= 4/15 fl oz per second
The answer is D . It increases by 35.25
To get the box plot we begin by arranging the data in ascending order:
<span>135, 149, 156, 112, 134, 141, 154, 116, 134, 156
rearranging we get:
112,116, 134, 134, 135, 141, 149, 154, 156, 156
then:
Lower value=112
Q1=134
Median=(135+141)/2=138
Q3=154
Largest value=156
The second figure is the correct figure.
