Answer:
The correct option is A.
Step-by-step explanation:
The given number is

Where 5 is dividend and 11 is divisor.
Since dividend is less than divisor we add a decimal place and the first zero. Notice the decimal point which has appeared on the answer line and by the dividend. It does not appear anywhere else.
Now the dividend is 50. Divide the number by divisor.

Subtract 44 from 50.

Therefore remainder is 6. Place a zero after 6.
Now the new dividend is 60. Divide the number by divisor.

Subtract 55 from 60.

Therefore remainder is 5.


Therefore option A is correct.
Answer:
528 dollars
Step-by-step explanation:
The starting price is $600. And it goes down by 20% then comes back up 10% so steps are:
First we got 20% off so I did 100 - 20 and got 80%
1: 80% * 600 = 80/100 * 600 = 480
Then we get an increase of 10% so I multiplied 110% with 480 which was our new price
2. 110/100 * 480 = 11 * 48(simplifying)
= 528
Isolate y: 2x-15(20+x)=-1
isolate x: 20-23 = -3
substitute: x = -23
answer: (-23, -3)
