Paul sold 105 more vanilla wafers than apricot wafers on Monday. On Tuesday, the number of apricot wafers he sold decreased by 40% while the number of vanilla wafers he sold remained the same. He sold each tart for $1.80. He sold a total of 385 wafers on Tuesday. How much money did he receive from the sale of wafers on both days?

	Vanilla wafers	Apricot wafers	Total
Comparing vanilla and apricot wafers  at first	105 more
Before	5 u + 105	5 u	10 u + 105
Change		- 2 u
After	5 u + 105	3 u	8 u + 105

40% = ⁴⁰₁₀₀ = ²₅

Total number of wafers sold on Tuesday
= 5 u + 105 + 3 u
= 8 u + 105

8 u + 105 = 385
8 u = 385 - 105
8 u = 280 

1 u = 280 ÷ 8 = 35

Total number of wafers sold on Monday
= 5 u + 105 + 5 u
= 10 u + 105

Total number of wafers sold on both days
= 8 u + 105 + 10 u + 105
= 18 u + 210
= 18 x 35 + 210
= 630 + 210
= 840

Total amount received from the sale of wafers on both days
= 840 x 1.80
= $1512

Answer(s): $1512
