3% = $12
1% = $4
100% = $400
8% = $32
400 + 32 = 432

Let's start with the following word equation: (total cost including 8% tax) - (total cost including 5% tax) = $12
Let x = the cost of the purchase (without tax)
So we can write: (x + 8% of x) - (x + 5% of x) = $12
In other words: (x + 0.08x) - (x + 0.05x) = $12
Simplify: 0.03x = 12
Solve: x = 12/0.03 = 1200/3 = 400
So, the cost of the purchase (without tax) is $400
So, the total amount Connie paid = $400 + (8% of $400) = $432
Answer: E
