On Thursday, the number of banana biscuits he sold decreased by 60% while the number of cheese biscuits he sold remained the same. He sold each tart for $2.60. He sold a total of 292 biscuits on Thursday. How much money did he receive from the sale of biscuits on both days?

	Cheese biscuits	Banana biscuits	Total
Comparing cheese and banana biscuits  at first	103 more
Before	5 u + 103	5 u	10 u + 103
Change		- 3 u
After	5 u + 103	2 u	7 u + 103

60% = ⁶⁰₁₀₀ = ³₅

Total number of biscuits sold on Thursday
= 5 u + 103 + 2 u
= 7 u + 103

7 u + 103 = 292
7 u = 292 - 103
7 u = 189 

1 u = 189 ÷ 7 = 27

Total number of biscuits sold on Wednesday
= 5 u + 103 + 5 u
= 10 u + 103

Total number of biscuits sold on both days
= 7 u + 103 + 10 u + 103
= 17 u + 206
= 17 x 27 + 206
= 459 + 206
= 665

Total amount received from the sale of biscuits on both days
= 665 x 2.60
= $1729

Answer(s): $1729
