Gabby had 95 grey erasers and 60 yellow erasers. Gabby gave away 40% of her grey erasers and 70% of her yellow erasers. What percentage of her erasers left was yellow?
Percentage of grey erasers left
= 100% - 40%
= 60%
Number of grey erasers left
= 60% x 95
= 60100 x 95
= 57
Percentage of yellow erasers left
= 100% - 70%
= 30%
Number of yellow erasers left
= 30% x 60
=
30100 x 60
= 18
Total number of erasers left
= 57 + 18
= 75
Percentage of erasers left that are yellow
=
1875 x 100%
= 24%
Answer(s): 24%
