0.3 of the green markers and 0.2 of the purple markers is 40.0.4 of the green markers and 0.3 of the purple markers is 55. What is the total number of green and purple markers?

1 answer

Let's assume the total number of green and purple markers is x.
0.3x + 0.2x = 40
0.5x = 40
x = 40 / 0.5
x = <<40/0.5=80>>80

0.4 of the green markers and 0.3 of the purple markers is 55.
0.4(0.3x) + 0.3(0.7x) = 55
0.12x + 0.21x = 55
0.33x = 55
x = 55 / 0.33
x = <<55/0.33=166.6667>>166.6667

The total number of green and purple markers is approximately 166.6667.
