Suppose a certain item used to sell for 30 cents per pound, and you see that it’s been marked up to 45 cents per pound. What is the percent increase?

50%

Step-by-step explanation:

45 cents is 15 cents more than 30 cents. The increase in cents is 15.

15 is half of 30. Half is also 0.5, 1/2, or 50%. The increase is 50%.

You can also answer this using the percent change formula.

percent change = (new number - old number)/(old number) * 100%

percent change = (45 - 30)/30 * 100%

percent change = 15/30 * 100%

percent change = 0.5 * 100%

percent change = 50%

If the result is positive, it is a percent increase.

If the result is negative, it is a percent decrease.

what are the options? ?

step-by-step explanation:

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
