Question

Bobbi collected plastic drink bottles and cans that could be recycled to raise money for his school. A recycle depot paid him $0.05 per can and $0.10 per plastic bottle that he brought in

If he raised over $80, what is the minimum number of plastic bottles he collected if he only collected 480 cans?
plastic bottles

Answer 1

Explanation:

.05c+.1b>80, if 480 cans were collected

.05(480)+.1b>80

24+.1b>80

.1b>56

b>560

So the minimum number of bottles collected is 561
