Question

You recycled a total of 30 cans and bottles and made $1.80. For cans you get $0.05 and for bottles

you get $0.15. How many cans did you recycle?

Answer 1

27

Explanation:

x + y = 30

0.05x + 0.15y = 1.80

x = 30 - y

1.5 - 0.05y + 0.15y = 1.80

0.10y = 0.30

y = 3 (bottles)

x = 27 (cans)
