Linda baked 80 croissants. ⁵₈ of the croissants were vanilla croissants. The rest were chocolate croissants. She gave an equal number of vanilla croissants and chocolate croissants away and had 5 times as many vanilla croissants as chocolate croissants left. How many croissants did she give away?

	Vanilla croissants	Chocolate croissants	Difference
Before	5x2 = 10 u	3x2 = 6 u	2x2 = 4 u
Change	- 5 u	- 5 u
After	5x1 = 5 u	1x1 = 1 u	4x1 = 4 u

Since Linda gave away an equal number of vanilla croissants and chocolate croissants, the difference in the number of vanilla croissants and chocolate croissants remains unchanged.  Make the difference in the vanilla croissants and chocolate croissants the same.  LCM of 2 and 4 is 4.

Total number of croissants at first
= 10 u + 6 u
= 16 u

16 u = 80

1 u = 80 ÷ 16 = 5

Number of croissants that Linda gave away
= 5 u + 5 u
= 10 u
= 10 x 5 
= 50

Answer(s): 50
