A label calls for a granular pesticide to be applied at 5 ounces per 1,000 feet of row. You must treat 10 rows, each 1/4 mile long. How much product is needed?

Explanation:
When a rate is given per 1,000 feet of row, you scale the amount to the total row footage. Here, there are 10 rows each 1/4 mile long. Convert to feet: 1/4 mile is 1,320 feet, so one row is 1,320 feet. Ten rows add up to 13,200 feet of row. At 5 ounces per 1,000 feet, the total amount needed is 5 × (13,200 ÷ 1,000) = 5 × 13.2 = 66 ounces. So the required product is 66 ounces.
