On Friday, the number of chocolate chip tarts he sold decreased by 60% while the number of banana tarts he sold remained the same. He sold each tart for $4.70. He sold a total of 256 tarts on Friday. How much money did he receive from the sale of tarts on both days?

	Banana tarts	Chocolate chip tarts	Total
Comparing banana and chocolate chip tarts  at first	74 more
Before	5 u + 74	5 u	10 u + 74
Change		- 3 u
After	5 u + 74	2 u	7 u + 74

60% = ⁶⁰₁₀₀ = ³₅

Total number of tarts sold on Friday
= 5 u + 74 + 2 u
= 7 u + 74

7 u + 74 = 256
7 u = 256 - 74
7 u = 182 

1 u = 182 ÷ 7 = 26

Total number of tarts sold on Thursday
= 5 u + 74 + 5 u
= 10 u + 74

Total number of tarts sold on both days
= 7 u + 74 + 10 u + 74
= 17 u + 148
= 17 x 26 + 148
= 442 + 148
= 590

Total amount received from the sale of tarts on both days
= 590 x 4.70
= $2773

Answer(s): $2773
