To find the average, you have to add everything up and divide by the amount that you have. In this case, you need to add together 160.5, 165.75 and 152.25, and then divide by 3.
160.5+165.75+152.25= 478.5
You've then got to divide this by three.
478.5/3= 159.5
Therefore, the average hour worked each month bu the employee is 159.5
Hope this helps :)

The cost of a plane ticket increases by 12%. After the increase, the ticket costs $616. What was the cost before the increase? E

Zina [86]

The cost before increase was $550.

Step-by-step explanation:

Given,

Increased price of plane ticket = $616

Increase percent = 12%

Let,

x be the original price of ticket.

Now,

The original price is 100% and 12% is increased, therefore;

New price = (100+12)% = 112%

Thus;

$616 is 112% of x.

112% of x = 616

$\frac{112}{100}x=616\\1.12x=616$

Dividing both sides by 1.12

$\frac{1.12x}{1.12}=\frac{616}{1.12}\\x=550$

The cost before increase was $550.
