Pamela made some croissants. She sold ⁴₅ of them in the morning and ²₅ of the remainder in the evening. If she sold 54 more croissants in the morning than in the evening, how many croissants did she make altogether?

Morning	Remainder		Total
4x5	1x5		5x5
	Evening	Left
	2	3
20 u	2 u	3 u	25 u

Fraction of croissants left after selling some in the morning
= 1 - ⁴₅ 
= ¹₅

Fraction of croissants sold in the evening
= ²₅ x ¹₅
= ²₂₅

Make the denominators the same.
 ⁴₅ = ²⁰₂₅ 

Number of croissants that Pamela sold in the morning = 20 u
Number of croissants that Pamela sold in the evening = 2 u

Number of more croissants that Pamela sold in the morning than in the evening
= 20 u - 2 u
= 18 u

18 u = 54

1 u = 54 ÷ 18 = 3

Total number of croissants that Pamela made
= 25 u
= 25 x 3
= 75

Answer(s): 75
