B. 0.06 ounce

C. 0.21 ounce

D. 0.36 ounce

Answer 1

B. 0.06 ounce

Explanation:

The mixture prepared by Chuck is enough for 14 plants.

If Chuck only used it, according to the recommended amount, for 12 plants, then only 12/14 parts of the 0.42 ounces of plant food were used and 2/14 parts still remain the watering can. The amount of plant food left, in ounces, is:

`F=0.42*(2)/(14)\\ F=0.06\ ounce`

0.06 ounce is left in the watering can.
