Susie and Britney each keep chickens, of two different breeds. Susie has 11 Rhode Island Reds and 6 Golden Comets. Britney has twice as many Rhode Island Reds as Susie, but only half as many Golden Comets. How many more chickens are in Britney's flock than in Susie's? Let's be accurate as possible.
Britney has 11 * 2 = 22 Rhode Island Reds. She has 6 / 2 = 3 Golden Comets. She has 22 + 3 = 25 total. Susie has 11 + 6 = 17 total. Britney has 25 - 17 = 8 more.
The answer: 8.
