B) 20
C) 30
D) 40

Answer 1

There are C)30 more yellow chairs than blue chairs.

Step-by-step explanation:

To find out how many more yellow chairs there are than blue chairs, we first need to determine the number of chairs of each color.

Given that the ratio of blue chairs to yellow chairs is 1 to 4, let's assume there are x blue chairs. Then the number of yellow chairs is 4x.

We know that the total number of chairs is 50, so we can set up the equation: x + 4x = 50. Simplifying this equation, we get 5x = 50, and solving for x gives us x = 10. Therefore, there are 10 blue chairs and 4x = 4(10) = 40 yellow chairs.

To find out how many more yellow chairs there are than blue chairs, we subtract the number of blue chairs from the number of yellow chairs: 40 - 10 = 30. Therefore, there are 30 more yellow chairs than blue chairs.
