It is trying to find the markup rate of how much you are selling them for from how much they are transported. We can see that 100% of $0.95 is $0.95 itself. 50% of $0.95 is half of that so we would get $0.48 .

Now we take the difference of the price they are sold at and the price they are transported. $1.99-$0.95= $1.04. This tells us that the markup rate must be higher than 100% because the difference is more than the initial value of $0.95. Now the difference between that is $1.04-$0.95 = $0.09. We need to find the percentage of $0.09 in $0.95. 10% of $0.95 is $0.095 but $0.095 is a little greater than $0.09 so we can assume it is %9.5

We add %9.5 to %100 and get a markup of %109.5

Mesha is comparing 1/3 and 3/5 using benchmarks 0 and 1. Which statements are correct? Check a that apply.
Dennis_Churaev [7]

Answer:

A, C

Step-by-step explanation:

Let's use a different benchmark for this: 1/2. Half of 5 is 2 1/2, so 3/5 is clearly <em>bigger</em> than 1/2 (since 3 is bigger than 2 1/2). Half of 3 is 1 1/2, so 1/3 is clearly <em>smaller</em> than a half (since 1 is smaller than 1 1/2). We have

1/3 < 1/2 < 3/5

Which, of course, implies that <em>1/3 is less than 3/5</em>, and by being smaller, <em>1/3 is closer to 0 than to 1</em>.

What is the solution of this linear system ? 3x + y = -2 y = -x +4
NeTakaya
The answer is as follows 
x = -3
y = 7


There are a few ways to do this but lets do it the following way.


<span>3x + y = -2
y = -x +4 <--- turn this to standard form
</span>
y = -x + 4
x + y = 4

3x + y = -2
x + y = 4 <---- Times this by -3 to cancel out

3x + y = -2
-3(x + y) = 4 * -3

3x + y = -2
-3x -3y =  -12

+ y = -2
 -3y =  -12

-2y = - 14

-2y / -2 = - 14 / -2

y = 7

Now that we found y we can insert 7 into the y position in one of the equation. For instance 

y = -x +4
7 = -x + 4
7 = -x + 4
-4 + 7 = -x
3 =  -x
x = -3
