Paul sold 120 more apple tarts than banana tarts on Tuesday. On Wednesday, the number of banana tarts he sold decreased by 20% while the number of apple tarts he sold remained the same. He sold each tart for $1.50. He sold a total of 336 tarts on Wednesday. How much money did he receive from the sale of tarts on both days?

	Apple tarts	Banana tarts	Total
Comparing apple and banana tarts  at first	120 more
Before	5 u + 120	5 u	10 u + 120
Change		- 1 u
After	5 u + 120	4 u	9 u + 120

20% = ²⁰₁₀₀ = ¹₅

Total number of tarts sold on Wednesday
= 5 u + 120 + 4 u
= 9 u + 120

9 u + 120 = 336
9 u = 336 - 120
9 u = 216 

1 u = 216 ÷ 9 = 24

Total number of tarts sold on Tuesday
= 5 u + 120 + 5 u
= 10 u + 120

Total number of tarts sold on both days
= 9 u + 120 + 10 u + 120
= 19 u + 240
= 19 x 24 + 240
= 456 + 240
= 696

Total amount received from the sale of tarts on both days
= 696 x 1.50
= $1044

Answer(s): $1044
