I say the answer is d I might be wrong.
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%
Answer:
D
Step-by-step explanation:
If you look at the right side of each piecewise function, you will see the x-values. That is what we will be focusing on in this explanation. All four equations have x <u>></u> 4, and we know that to be true. If you look at the equation on the graph going South West, you will see that the endpoint is at x=1. Only 1 equation, D, has this in the piecewise function. To confirm it is D, you can see that 1<x<4 is also in the piecewise function, and all the values line up with their corresponding y-values.
Hope this helps! :)

Answer:
2/5
Step-by-step explanation:
in 4/10, both the numerator (4) and denominator (5) are multiples of 2, as 4 = 2 * 2 and 10 = 2 * 5. thus, we can divide both the numerator and denominator by 2 to get
(4/2) / (10/2) = 2/5 as our answer.
