First, convert square feet to square yards: 955 sq ft / 9 (since 1 sq yd = 9 sq ft) = 106.11 sq yds. Then, divide by the coverage of one gallon: 106.11 sq yds / 15 sq yds/gallon = 7.07 gallons. Since you can't buy a fraction of a gallon, you'd round up, but the closest answer choice given is 7.1 gallons.
