The amount of paint a painter needs is directly proportional to the area of the object he is painting. if a painter needs g gallons of paint for every s square feet that he paints, what is the total amount of paint that he needs to paint a house in terms of g and s?
a) gs
b) g - s
c) g + s
d) g/s

The answer for your question would be A. gs for the amount of paint that he needs to  paint a house in terms.

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.

Bis the answer! hope this
