Question

every yellow marble is expensive.one -half the orange marbles are expensive.one -half of all expensive marbles are yellow. there are 40 yellow marbles and 25 expensive marbles that are niether yellow nor orange. how many orange marbles are there?

Answer 1

if every yellow is expensive, there are 40 expensive marbles that are yellow

half the expensives are yellow, meaning there are 80 expensive marbles in all.

That means there are 40 expensives that are not yellow.

there are 25 expensives that are not orange (or yellow). There are 40 non-yellow expensives.

So, there are 15 expensive orange marbles, and that's half of all the oranges.

There are 30 orange marbles.

Answer 4

To determine the number of orange marbles, let's break down the given information and use logical steps to find the answer.

1. The information states that every yellow marble is expensive, which means all yellow marbles are expensive.
2. It also states that one-half of the orange marbles are expensive. So, 50% of the orange marbles are expensive, but we don't know the total number of orange marbles yet.
3. Lastly, it states that one-half of all expensive marbles are yellow. Since there are 40 yellow marbles, this means that there are 40 x 2 = 80 expensive marbles in total.

Now, let's solve the problem step by step:

1. Calculate the total number of expensive marbles:
- In the information provided, it states that there are 25 expensive marbles that are neither yellow nor orange. Therefore, we subtract these marbles from the total number of expensive marbles to get the remaining expensive marbles: 80 - 25 = 55 expensive marbles.

2. Calculate the number of orange marbles that are expensive:
- Since one-half of the orange marbles are expensive, we divide the number of expensive marbles by 50% to find the total number of orange marbles: 55 ÷ 0.5 = 110 orange marbles.

3. Calculate the number of orange marbles that are not expensive:
- To find the number of orange marbles that are not expensive, we subtract the number of expensive orange marbles from the total number of orange marbles: 110 - 55 = 55 orange marbles that are not expensive.

Therefore, there are 110 orange marbles in total.
