Basically find the percentage of lightbulbs that are bad. 5/136. So about 3. 6 percent. I'm going to use a more exact form of this percent for my calculations though. Now use the decimal for of this (0.036....) and multiply it by 2720. Using my exact decimal, the answer just so happened to be exactly 100. So there will be 100 defective lightbulbs per day. (Teachers are a stickler for units, so don't forget them if it's for a teacher)
R+p=28 → p=28-r 2r+28-r=43 → r=15 p=28-15=13 Bruce has 15 Orioles cards and 13 Pirates cards Mila has 30 Orioles cards and13 Pirates cards So they have 45 Orioles cards and 26 Pirates cards
