The answers to the questions on how she would use the colored chips are given here:

  • brochure 4 blue chips
  • writing a new article 6 yellow chips
  • designing a computer presentation 10 red chips

How to solve for the values

For the first percentage

20 / 100 = x/20

= 20 * 20 = 100x

400 = 100x

divide through by 100

x = 400/100

x = 4

For the second percentage

30/100 = x/20

600 = 100x

x = 600/100

x = 6

For the last

50/100 = x/20

1000 = 100x

x = 10

The proof is that 6 + 4 + 10 still gives us 20
