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.

The difference of two numbers is 90 and their quotient is 10
bija089 [108]
To solve this, set up two equations using the information you're given. Let's call our two numbers a and b:
1) D<span>ifference of two numbers is 90
a - b (difference of two numbers) = 90

2) The quotient of these two numbers is 10
a/b (quotient of the two numbers) = 10


Now you can solve for the two numbers.
1) Solve the second equation for one of the variables. Let's solve for a:
a/b = 10
a = 10b

2) Plug a =10b into the first equation and solve for the value of b:
a - b = 90
10b - b = 90
9b = 90
b = 10

3) Using b = 10, plug it back into one of the equations to find the value of a. I'll plug it back into the first equation:
a - b = 90
a - 10 = 90
a = 100
