grade 5 math
posted by Jeff .
the grade 5 class decided to collect cans of food to donate to the food bank .After the 1st week ,they had collected 8 cans . The next week they collected 11 more . By the 3 rd week they had 31 cans
Following this pattern how long will it take for them to reach there goal of 150 cans
Thank you for helping
8+11+31=50 for 3 weeks and to get 150 cans you would need to collect for 6 more weeks.
Look for the pattern. The class started with 8 the first week, then added 11 for a total of 19 after week 2. Week 3, they had 31 cans. How many more is that than week 2? 12, right? Week 2 was +11, week 3 was +12, week 4 will be +13, for a total of 44, and week 5 will be +14 and the class will have 58 cans. See the pattern? You can do the rest from here.
Tim's family was collecting aluminium cans to recycle.They found out that they would get two cents for every three cans they collected.If they collected 2,187 cans,how much money did they receive?
