A weight of 15 ounces stretches a spring 10 inches. A weight of 24 ounces stretches the same spring 16 inches.

How many inches does the spring stretch per ounce of additional weight?

16-10 = 6 inches

24-15 = 9 ounces

it stretches 6 inches when 9 ounces are added

divide 6 inches by 9 ounces

6 / 9 = 0.67 inches per ounce
