On Thursday, the number of strawberry cupcakes he sold decreased by 20% while the number of apricot cupcakes he sold remained the same. He sold each tart for $2.20. He sold a total of 275 cupcakes on Thursday. How much money did he receive from the sale of cupcakes on both days?

	Apricot cupcakes	Strawberry cupcakes	Total
Comparing apricot and strawberry cupcakes  at first	140 more
Before	5 u + 140	5 u	10 u + 140
Change		- 1 u
After	5 u + 140	4 u	9 u + 140

20% = ²⁰₁₀₀ = ¹₅

Total number of cupcakes sold on Thursday
= 5 u + 140 + 4 u
= 9 u + 140

9 u + 140 = 275
9 u = 275 - 140
9 u = 135 

1 u = 135 ÷ 9 = 15

Total number of cupcakes sold on Wednesday
= 5 u + 140 + 5 u
= 10 u + 140

Total number of cupcakes sold on both days
= 9 u + 140 + 10 u + 140
= 19 u + 280
= 19 x 15 + 280
= 285 + 280
= 565

Total amount received from the sale of cupcakes on both days
= 565 x 2.20
= $1243

Answer(s): $1243
