Question

a gumball machine contains 23 green gumballs, 52 red gumballs, 34 blue gumballs, 61 yellow gumballs, and 30 pink gumballs. what percent of the gumballs are red? (ignore the % symbol when entering your answer. for example, if the answer is 12%, enter 12.)

Explanation:

Step1: Calculate total number of gumballs

Add up the number of each color: \(23 + 52+34 + 61+30=\sum_{i}n_i\).

Step2: Calculate the percentage of red gumballs

The formula for percentage is \(\text{Percentage}=\frac{\text{Number of red gumballs}}{\text{Total number of gumballs}}\times100\).
Substitute the values: \(\frac{52}{200}\times100\).
Since \(\frac{52}{200}=\frac{52\div2}{200\div2}=\frac{26}{100}\), then \(\frac{26}{100}\times100 = 26\).

Answer:

26
