Answer: Amount of change : $30
percent increase : 200%
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
- <em>Wholesale price: $15
</em>
- <em>Retail price: $45
</em>
To obtain the amount of change we have to subtract the wholesale price to the retail price:
Mathematically speaking:
45 -15 = $30
For the percent increase, the amount of change (30) is some percent of the original price (15). So:
30 / 15 =2 (decimal form)
If we multiply it by 100, the percentage is:
200%
Easy! just compare then cross multiply 70:1 × 10:4 because you need to use the negative reciprocal of either one to create division with ratios/fractions
You solve an expression for a variable if that variable sits alone on one side of the equation, and everything else is on the other side.
So, our goal is to leave
alone on the right hand side, and move everything else to the left.
So, we start with

We multiply both sides by 3:

We divide both sides by 

To compute the required height, simply plug in the values:

p-2-3 =-8+3+5p-4p
Let us try to simplify this equation,
combining like terms -2-3 on left and 5p-4p and -8+3 on the right side,
p-5=-5+p
Since we have +p on both sides , so both of them will get cancelled,
-5=5
Here we have no variable left and also -5 is not equal to 5.
so answer will be no solution for the given equation.
