He sold each tart for $5.20. He sold a total of 210 scones on Tuesday. How much money did he receive from the sale of scones on both days?

	Blueberry scones	Cherry scones	Total
Comparing blueberry and cherry scones  at first	90 more
Before	5 u + 90	5 u	10 u + 90
Change		- 2 u
After	5 u + 90	3 u	8 u + 90

40% = ⁴⁰₁₀₀ = ²₅

Total number of scones sold on Tuesday
= 5 u + 90 + 3 u
= 8 u + 90

8 u + 90 = 210
8 u = 210 - 90
8 u = 120 

1 u = 120 ÷ 8 = 15

Total number of scones sold on Monday
= 5 u + 90 + 5 u
= 10 u + 90

Total number of scones sold on both days
= 8 u + 90 + 10 u + 90
= 18 u + 180
= 18 x 15 + 180
= 270 + 180
= 450

Total amount received from the sale of scones on both days
= 450 x 5.20
= $2340

Answer(s): $2340
