The correct option is b. 60 if there are 80 blue balls by setting up a proportion using the given ratio and the number of blue balls.
To find the number of red ball to determine the ratio between red and blue balls. In this case, the ratio is 3:4 (red to blue).
Let x represent the number of red balls.
The proportion can be set up as
(3/4) = x/80.
Cross-multiplying gives:
4x = 3 * 80,
which simplifies to
4x = 240.
Dividing both sides of the equation by 4,gives:
x = 60.
Therefore, there are 6in the box by using ratio and proportion

Answer:
Step-by-step explanatioidkn:
The artist will need 49 ounces of blue.
To find out how many ounces of blue the artist will need, we need to determine the ratio of blue to yellow. Since the artist realized she has 49 ounces of yellow left, we can assume she had the same amount of blue before. As stated in the problem, 50% of the flowers are blue, so we can represent this ratio as 1:1. Therefore, the artist will need 49 ounces of blue.
