340 pounds of paper and 108 pounds of cans will be collected by students in September and October combined.
Step-by-step explanation:
Given,
Paper collected in September = x = 85 pounds
Cans collected in September = y = 18 pounds
Goals for October;
Paper = Three time the amount of September
Paper = 3x
Paper = 3(85) = 255 pounds
Cans = Five times the amount of September
Cans = 5y
Cans = 5(18) = 90 pounds
Total amount of paper collected = Amount of September + Amount of October
Total amount of paper collected = 85+255 = 340 pounds
Total amount of cans collected = Amount of September + Amount of October
Total amount of cans collected = 18+90 = 108 pounds
340 pounds of paper and 108 pounds of cans will be collected by students in September and October combined.
