Of the 60 students who auditioned in a singing contest, 40% were asked to come back for a second audition. After the second audition, 6 students were asked to come back for a final audition. What percent of change was there from the second audition to the final audition?

25%

Step-by-step explanation:

In order to solve this problem we first need to figure out how many students were in the second audition. We calculate this by multiplying the 60 initial students by the 40% that made it to the second audition but in a decimal form which is 0.4 (40 / 100 = 0.4)

60 * 0.4 = 24 students

Now that we know that 24 students made it to the second audition and only 6 made it to the final audition we can divide the number of students in the final audition by those in the second audition to find out the percent of change.

6 / 24 = 0.25 multiply by 100 to turn decimal into a percentage.

0.25 * 100 = 25%

We can see now that the percentage of change is 25%

answer: when you burn wood, the carbon reacts with the oxygen in the air to create ash and smoke. that is a permanent change you cannot undo that.

step-by-step explanation:

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75
