Answer: Brain paid $ 45.5 for the jacket.
Step-by-step explanation:
Given: Original price of jacket = $ 65
Discount -= 30%
Price after discount = Original price - 30% of Original price
= 65 - 30% of 65
= 65 - (0.3) x 65 [30% = 0.3]
= (65) (1-0.3 ) [Taking 65 common]
= (65)(0.7)
= $ 45.5
Hence, Brain paid $ 45.5 for the jacket.
