Marion had 105 green pens and 56 purple pens. Marion gave away 20% of her green pens and 50% of her purple pens. What percentage of her pens left was purple?
Percentage of green pens left
= 100% - 20%
= 80%
Number of green pens left
= 80% x 105
= 80100 x 105
= 84
Percentage of purple pens left
= 100% - 50%
= 50%
Number of purple pens left
= 50% x 56
=
50100 x 56
= 28
Total number of pens left
= 84 + 28
= 112
Percentage of pens left that are purple
=
28112 x 100%
