Answer:
5
Step-by-step explanation:
it absolutely depends on how fast you study
So here, we are starting with two numbers: the original price, and the price after the percent increase.
First, we need to find the differences between the prices to figure out how much of a difference the percent made. $181.09 - $102.30 = $78.79
$78.79 is how much money the original price was increased by. We can find the percent change using this, since this number is what percent of the original price went up.
So now: $78.78 / $102.30 = .77018
And now, we convert that to percent: 77%
The markup was 77%.
Answer: 93
Step-by-step explanation:
To solve this we need to follow BIDMAS.
The order of calculations is brackets, division, then multiplication, then addition, then subtraction.
1) (4 + 3) = 7
2) Division: 8 / 2 = 4
3) Multiplication: 3 * 32 = 96
This leaves us with:
96 + 4 - 7
This equals 93.
Yes. I think so. Even if there is not intercept the intercept is 0
Ryan's marbles = x
Marie has 4 times less marbles then Ryan would have if he lost 15 marbles (it means he would have x-15)
So, Marie marbles = (x-15):4
If Ryan lost 75 marbles (it means he would have x-75), he would have 1 1/2 times as many marbles as Marie.
We got an equation:
Multiply both sides by 8:

Add 600 and subtract 3x on both sides:

Divide both sides by 5:

Answer: Ryan have 111 marbles.
