To find out how far up the bar for green will go in Kayla's percent bar graph, we need to calculate the percentage of green paper clips in relation to the total number of paper clips.
Kayla has 15 green paper clips out of a total of 50 paper clips. The percentage can be calculated using the formula:
\[ \text{Percentage} = \left( \frac{\text{Number of green paper clips}}{\text{Total number of paper clips}} \right) \times 100 \]
Substituting the values:
\[ \text{Percentage} = \left( \frac{15}{50} \right) \times 100 = 0.3 \times 100 = 30% \]
Thus, the bar for green will go up to 30% in her bar graph.
The correct response is: up to 30%.
