Cindy made some croissants. She sold ³₄ of them in the morning and ³₁₀ of the remainder in the afternoon. If she sold 243 more croissants in the morning than in the afternoon, how many croissants did she make altogether?

Morning	Remainder		Total
3x10	1x10		4x10
	Afternoon	Left
	3	7
30 u	3 u	7 u	40 u

Fraction of croissants left after selling some in the morning
= 1 - ³₄ 
= ¹₄

Fraction of croissants sold in the afternoon
= ³₁₀ x ¹₄
= ³₄₀

Make the denominators the same.
 ³₄ = ³⁰₄₀ 

Number of croissants that Cindy sold in the morning = 30 u
Number of croissants that Cindy sold in the afternoon = 3 u

Number of more croissants that Cindy sold in the morning than in the afternoon
= 30 u - 3 u
= 27 u

27 u = 243

1 u = 243 ÷ 27 = 9

Total number of croissants that Cindy made
= 40 u
= 40 x 9
= 360

Answer(s): 360
