Use a proportion to solve the problem.
-If a spring stretches 5 meters when a 2 -kilogram weight is attached to it, how much will it stretch when a 16-kilogram weight is attached to it?
A) $40 \mathrm{~m}$
B) $39 \mathrm{~m}$
C) $42 \mathrm{~m}$
D) $43 \mathrm{~m}$

The stretch of the spring is directly proportional to the weight attached to it. So, if 2 kilograms cause a 5-meter stretch, 16 kilograms (which is 8 times more weight) will cause an 8 times greater stretch: $5 \mathrm{~m} \times 8 = 40 \mathrm{~m}$.
