He sold each tart for $3.30. He sold a total of 372 puffs on Saturday. How much money did he receive from the sale of puffs on both days?

	Cheese puffs	Apricot puffs	Total
Comparing cheese and apricot puffs  at first	68 more
Before	10 u + 68	10 u	20 u + 68
Change		- 1 u
After	10 u + 68	9 u	19 u + 68

10% = ¹⁰₁₀₀ = ¹₁₀

Total number of puffs sold on Saturday
= 10 u + 68 + 9 u
= 19 u + 68

19 u + 68 = 372
19 u = 372 - 68
19 u = 304 

1 u = 304 ÷ 19 = 16

Total number of puffs sold on Friday
= 10 u + 68 + 10 u
= 20 u + 68

Total number of puffs sold on both days
= 19 u + 68 + 20 u + 68
= 39 u + 136
= 39 x 16 + 136
= 624 + 136
= 760

Total amount received from the sale of puffs on both days
= 760 x 3.30
= $2508

Answer(s): $2508
