On Wednesday, the number of vanilla cupcakes he sold decreased by 25% while the number of chocolate chip cupcakes he sold remained the same. He sold each tart for $5.90. He sold a total of 248 cupcakes on Wednesday. How much money did he receive from the sale of cupcakes on both days?

	Chocolate chip cupcakes	Vanilla cupcakes	Total
Comparing chocolate chip and vanilla cupcakes  at first	150 more
Before	4 u + 150	4 u	8 u + 150
Change		- 1 u
After	4 u + 150	3 u	7 u + 150

25% = ²⁵₁₀₀ = ¹₄

Total number of cupcakes sold on Wednesday
= 4 u + 150 + 3 u
= 7 u + 150

7 u + 150 = 248
7 u = 248 - 150
7 u = 98 

1 u = 98 ÷ 7 = 14

Total number of cupcakes sold on Tuesday
= 4 u + 150 + 4 u
= 8 u + 150

Total number of cupcakes sold on both days
= 7 u + 150 + 8 u + 150
= 15 u + 300
= 15 x 14 + 300
= 210 + 300
= 510

Total amount received from the sale of cupcakes on both days
= 510 x 5.90
= $3009

Answer(s): $3009
