If Gabrielle earned a weekly salary of $235.00 and earns 8% of the sales over $500, let's work to find what her weekly pay was if she had $6,250.00 in sales.

Now, our question tells that she get 8% commission of sales over $500.00.
If she made $6,250.00 in sales, then she would earn a "bonus" of 8% of her sales.

8% of $6,250 = $500.00

Her weekly salary is $235.00. Adding her "bonus" of the 8% of sales ($500.00), we would perform this equation:

$235.00 + $500.00 = $735.00

Her total pay for that week is:

$735.00, is your answer.

Three brothers Charlie Robert and Nicholas have 21 video games Charlie has twice as many games as Robert. Robert has 5 fewer gam

AVprozaik [17]

Answer:

The equation would be $4x-15=21$ .

Step-by-step explanation:

Given;

Total Number of Video games = 21

Let the number of video game Nicholas has be 'x'.

Now Given:

Robert has 5 fewer games than Nicholas.

so we can say that;

number of video game Robert has = $x-5$

Also Given:

Charlie has twice as many games as Robert.

so we can say that;

number of video game Charlie has = $2(x-5)=2x-10$

we need to write the equation.

Solution:

Now we can say that;

Total Number of Video games is equal to sum of number of video game Nicholas has, number of video game Robert has and number of video game Charlie has.

framing the equation we get;

$x+x-5+2x-10=21\\\\4x-15=21$
