Answer:
120
Explanation:
The total number of medals won is 150, and the circle graph shows that the proportion of medals won as gold is 20 percent, as silver is 30 percent, and as bronze is 50 percent.
To find the number of gold and bronze medals won, we need to calculate the total number of medals won in each category by multiplying the total number of medals by the proportion of medals won in each category.
Gold medals: 150 * 20% = 30
Bronze medals: 150 * 50% = 75
So, a total of 30 + 75 = 105 medals were won as gold and bronze.
