Oprah makes $156.00 per day plus an additional 8% commission on her sales. Which equation could be used to find how much Oprah m
Natasha_Volkova [10]

Answer:

The answer is <u>C.</u>  0.08x + $156.00 = r.

Step-by-step explanation:

Given:

Oprah makes $156.00 per day plus an additional 8% commission on her sales.

She sold x dollars worth.

Now, to find equation how much Oprah made in one day, r.

As. given in question:

She makes per day = $156.00.

Worth of sold = x.

Commision on her sales = 8%.

And one day = r.

Now, to get the equation Oprah made in one day:

r=\$156.00+8\%\ of\ x.

r=\$156.00+\frac{8}{100} \times x

r=\$156.00+0.08\times x

r=\$156.00+0.08x

r=0.08x+\$156.00

0.08x+\$156.00=r

<em>Thus, the equation is</em>  0.08x+\$156.00=r.

Therefore, the answer is C.  0.08x + $156.00 = r.

8) The perimeter of a rectangle is 20x2 + xy - 7y2 and one of it's sides is
Sedbober [7]

Answer:

3x^2 + 3xy/2 - 7xy^2/2

Step-by-step explanation:

So we know the perimeter is 20x^2 + xy - 7y^2,

To find any perimeter you need 2l + 2w = P so,

One of the sides is 7x^2 - xy

First plug in the values,

2(7x^2-xy) + 2w = 20x^2 + xy - 7y^2

Multiply,

14x^2-2xy + 2w = 20x^2 + xy - 7y^2

Subtract,

14x^2 - 2xy - 14x^2 + 2xy + 2w = 20x^2 + xy - 7y^2 - 14x^2 + 2xy

2w = 6x^2 + 3xy - 7y^2

w = 3x^2 + 3xy/2 - 7xy^2/2
