Percentage of lollipops after Rael received from Eric
= 100% + 30%
= 130%
Percentage of Rael's lollipops that Emily had after receiving from Rael
= 50% x 130%
=
50100 x 130%
= 65%
Percentage of lollipops that Rael had left after giving to Emily
= 130% - 65%
= 65%
100% = 40
Number of lollipops that Rael had left
= 65% x 40
=
65100 x 40
= 26
