Replace temp with query

Temporary variables create additional locally scoped names and complicate extraction.

Before:

def calculateTotal():
    basePrice = quantity * itemPrice
    if basePrice > 1000:
        return basePrice * 0.95
    else:
        return basePrice * 0.98

After:

def calculateTotal():
    if basePrice() > 1000:
        return basePrice() * 0.95
    else:
        return basePrice() * 0.98
 
def basePrice():
    return quantity * itemPrice
