Answer:

Olivia babysat for a total of 15 hours.

Step-by-step explanation:

8.50(h) + 12 = 139.50

In order to get a direct result of the hours she

worked, we have to subtract 12 on both sides:

8.50(h) + 12 - 12 = 139.50 - 12

In order to fine the value of time she spent, we have to divide the amount of money she got on both sides:

8.50(h) = 127.5

8.50 = 8.50

h = 15

Therefore, Olivia babysat for a total of 15 hours.

Ksenya-84 [330]

Answer:

Step-by-step explanation:

At the end of any given business day, CFFC has 400-80t cases of perfume on hand, where t = 1 represents Monday, t = 2 represents Tuesday and so on. The inventory becomes nil on Friday evening. So,

The values of a and b are

a = 0

b = 5

Using the formular for average value, we have the average value as

$\frac{1}{5-0}\int\limits^5_0 {(400-80t)}dt\\\\=\frac{1}{5}(400t-\frac{80t^2}{2})\limits^5_0\\\\=\frac{1}{5}(400t-40t^2)\limits^5_0\\\\=\frac{1}{5}(2000-1000)\\\\=200$
