Describe how total job benefits and total employee compensation differ.

diamong [38]

Difference between total job benefits and total employee compensation:

Employee compensation:

The total employee compensation refers to the amount of money an employee is given in exchange for the tasks they complete for the employer.
Employee compensation is the most basic or we can say the minimum amount of money an employee is given. It mostly includes the salary of an employee.

Total job benefits:

Total job benefits are not necessarily provided in monetary means. As the name suggests, job benefits are the facilities and advantages provided by the company or the employer to the employees.
These benefits are generally performance- based, the better the performance, the better the benefits.
Job benefits may include health insurance policies, travel packages, transport facilities and much more.

A mistake was made in mixing the lemonade— PLEASE HELP!!

beks73 [17]

Answer:

Part A:

$4 + x = y$

$0.5*4 + 1*x = 0.7*y$

$x = 8/3\ quarts\ of\ 100\%\ solution$

$y = 20/3\ quarts\ of\ 70\%\ solution$

Part B:

$x + y = 10$

$2x + 3y = 23$

$x = 7$ and $y = 3$

Step-by-step explanation:

Part A:

The inicial concentration of the lemonade is 50%, and the volume is 4 quarts, and we will add x quarts of a lemonade with a concentration of 100%, so the total volume will be y, and the concentration will be 0.7, so we have that:

$4 + x = y$

$0.5*4 + 1*x = 0.7*y$

Using the value of y from the first equation in the second one, we have:

$2 + x = 0.7*(4 + x)$
