If there are 800 plants to treat and you plan to use 0.25 oz of spray per plant, how many ounces of spray solution are required?

• A. 200 oz
• B. 400 oz
• C. 800 oz
• D. 100 oz

Answer: (A)

The total amount of spray is found by multiplying the number of plants by the amount used per plant. For 800 plants at 0.25 oz each, multiply 800 × 0.25 to get 200 oz. Since 0.25 is a quarter, this is the same as 800 ÷ 4, which also equals 200. The other totals would require using more or less spray per plant than planned, so they don’t match the given scenario.
