A total of 600 advertisements were sold for a certain magazine. If 20 percent of the first 200 sold were in color, 40 percent of the next 300 sold were in color, and 80 percent of the last 100 sold were in color, what percent of the 600 advertisements were in color?

40%

Step-by-step explanation:

First, find how many of the first 200 were in color:

200(0.2)

= 40

Then, find how many of the next 300 were in color:

300(0.4)

= 120

Find how many of the last 100 were in color:

100(0.8)

= 80

Then, add these all together to find how many were in color:

40 + 120 + 80

= 240

Then, divide 240 by 600 to find the percent that were in color:

240/600

= 0.4

So, 40% of the 600 advertisements were in color
