##### Complexity:

time complexity is O(1)

space complexity is O(1)

##### Execution:

The cost for each present is either the cost of its category, or the cost of the other category + the conversion cost. Just select the minimum.

##### Solution:

#!/usr/bin/py if __name__ == '__main__': t = input() for _ in xrange(t): b, w = map(int, raw_input().split()) x, y, z = map(int, raw_input().split()) print min(b*x, b*(y+z)) + min(w*(x+z), w*y)
