Ken sold 90 more cranberry scones than banana scones on Friday. On Saturday, the number of banana scones he sold decreased by 25% while the number of cranberry scones he sold remained the same. He sold each tart for $2.50. He sold a total of 160 scones on Saturday. How much money did he receive from the sale of scones on both days?

	Cranberry scones	Banana scones	Total
Comparing cranberry and banana scones  at first	90 more
Before	4 u + 90	4 u	8 u + 90
Change		- 1 u
After	4 u + 90	3 u	7 u + 90

25% = ²⁵₁₀₀ = ¹₄

Total number of scones sold on Saturday
= 4 u + 90 + 3 u
= 7 u + 90

7 u + 90 = 160
7 u = 160 - 90
7 u = 70 

1 u = 70 ÷ 7 = 10

Total number of scones sold on Friday
= 4 u + 90 + 4 u
= 8 u + 90

Total number of scones sold on both days
= 7 u + 90 + 8 u + 90
= 15 u + 180
= 15 x 10 + 180
= 150 + 180
= 330

Total amount received from the sale of scones on both days
= 330 x 2.50
= $825

Answer(s): $825
