You have to use a system. the first would be x + y = 12 since she has 12 coins. the other equation would be 0.05x + 0.1y = 0.95 (an easier way is 5x + 10y = 95 if you clear it). now you just solve using substitution or elimination.
B.200 because 200x6 is 1200 and 100 is to little and 250 is too much so it’s b.
