Question

A bag contains counters that are red, black, or green. [1/3] are red, [1/6] are black. There are 15 green counters in the bag. How many black counters are in the bag?

A) 5
B) 10
C) 15
D) 20

Answer 1

To find the number of black counters, determine the total number of counters first and set up an equation.

Step-by-step explanation:

To find the number of black counters in the bag, we first need to determine the total number of counters in the bag. Given that [1/3] are red, [1/6] are black, and 15 are green, we can set up the equation:

Total counters = red counters + black counters + green counters

Substituting the given information:

Total counters = [1/3]x + [1/6]x + 15

Since the total number of counters is not given, we can't determine the exact number of black counters. Therefore, we cannot determine the answer from the given information. So, the answer is unknown or not enough information is provided.
