Robert collected 330 aluminum cans. If 100 aluminum cans weigh 4 pounds, and the recycling center is paying 25 cents a pound, how much will Robert be paid for his 330 cans?
This has a little bit of mental math but... since he has 330 u can automatically see he already has 12 pounds then when multiplied they would already pay him $3.00. so with the other 30 in 330..... so 25 can equal 1 pound.... so Robert would be payed $3.30
