Michael sold 120 more cherry cookies than apple cookies on Friday. On Saturday, the number of apple cookies he sold decreased by 25% while the number of cherry cookies he sold remained the same. He sold each tart for $3.80. He sold a total of 225 cookies on Saturday. How much money did he receive from the sale of cookies on both days?

	Cherry cookies	Apple cookies	Total
Comparing cherry and apple cookies  at first	120 more
Before	4 u + 120	4 u	8 u + 120
Change		- 1 u
After	4 u + 120	3 u	7 u + 120

25% = ²⁵₁₀₀ = ¹₄

Total number of cookies sold on Saturday
= 4 u + 120 + 3 u
= 7 u + 120

7 u + 120 = 225
7 u = 225 - 120
7 u = 105 

1 u = 105 ÷ 7 = 15

Total number of cookies sold on Friday
= 4 u + 120 + 4 u
= 8 u + 120

Total number of cookies sold on both days
= 7 u + 120 + 8 u + 120
= 15 u + 240
= 15 x 15 + 240
= 225 + 240
= 465

Total amount received from the sale of cookies on both days
= 465 x 3.80
= $1767

Answer(s): $1767
