$y = ( {x}^{2} + 2x + 1) - 1$

$y = ({x + 1})^{2} - 1$

$y = ({x + 1})^{2} - ({1})^{2}$

We're done now but I have something to tell...

A waiter earns $128 for six hours of work. The total included $86 in tips. How much does the waiter earn each hour??A waiter arm

Lady bird [3.3K]

Answer:

The waiter earns $7 per hour

Step-by-step explanation:

In this question, we are asked to calculate the amount a waiter earns per hour at work given the total he had earned including tips.

To solve this question, we can see that we have been given the total amount he has earned and also the amount he has also earned in tips.

Now, to get the standard amount he’s supposed to earn per hour, firstly, we have to subtract the amount he has earned in tips from the total. Mathematically that is 128-86 = $42

This means, by standard he has earned $42 in six hours. Now, we need to calculate the amount she earns by hour.

To do this, we simply divide the total amount earned by the number of hours.

Mathematically that is $42/6 hours = $7 per hour
