Janet buys a multi-flavor pack of cheese sticks. 15 of the sticks are cheddar, 30 are mozzarella, and 45 are pepperjack. If Janet picks a cheese stick at random, what is the percentage chance it will be pepperjack?
First find the total number of cheesesticks: 15 cheddar + 30 mozzarella + 45 pepperjack = <<15+30+45=90>>90 cheese sticks
Then divide the number of pepperjack sticks by the total number of cheese sticks and multiply by 100% to express the answer as a percentage: 45 pepperjack sticks / 90 cheese sticks * 100% = 50%
