Elyse made some biscuits. She sold ⁵₇ of them in the afternoon and ³₁₀ of the remainder in the evening. If she sold 242 more biscuits in the afternoon than in the evening, how many biscuits did she make altogether?

Afternoon	Remainder		Total
5x5	2x5		7x5
	Evening	Left
	3	7
25 u	3 u	7 u	35 u

Fraction of biscuits left after selling some in the afternoon
= 1 - ⁵₇ 
= ²₇

Fraction of biscuits sold in the evening
= ³₁₀ x ²₇
= ³₃₅

Make the denominators the same.
 ⁵₇ = ²⁵₃₅ 

Number of biscuits that Elyse sold in the afternoon = 25 u
Number of biscuits that Elyse sold in the evening = 3 u

Number of more biscuits that Elyse sold in the afternoon than in the evening
= 25 u - 3 u
= 22 u

22 u = 242

1 u = 242 ÷ 22 = 11

Total number of biscuits that Elyse made
= 35 u
= 35 x 11
= 385

Answer(s): 385
