On Sunday, the number of chocolate chip tarts he sold decreased by 70% while the number of strawberry tarts he sold remained the same. He sold each tart for $3.50. He sold a total of 382 tarts on Sunday. How much money did he receive from the sale of tarts on both days?

	Strawberry tarts	Chocolate chip tarts	Total
Comparing strawberry and chocolate chip tarts  at first	44 more
Before	10 u + 44	10 u	20 u + 44
Change		- 7 u
After	10 u + 44	3 u	13 u + 44

70% = ⁷⁰₁₀₀ = ⁷₁₀

Total number of tarts sold on Sunday
= 10 u + 44 + 3 u
= 13 u + 44

13 u + 44 = 382
13 u = 382 - 44
13 u = 338 

1 u = 338 ÷ 13 = 26

Total number of tarts sold on Saturday
= 10 u + 44 + 10 u
= 20 u + 44

Total number of tarts sold on both days
= 13 u + 44 + 20 u + 44
= 33 u + 88
= 33 x 26 + 88
= 858 + 88
= 946

Total amount received from the sale of tarts on both days
= 946 x 3.50
= $3311

Answer(s): $3311
