Material A: tested load 20 N; mass 12 g; cost 4 tokens. Material B: tested load 16 N; mass 8 g; cost 3 tokens. Material C: tested load 19 N; mass 9 g; cost 6 tokens.
A model needs a material tested for at least 18 N while weighing no more than 10 g. Which listed material has the lowest cost among those meeting both limits?
- Material A
- Material C
- Ignore the mass limit.
- Material B
See the answer & why
Material C
First remove materials failing either limit. Material C has the lowest stated cost among the remaining options.
A little hint: Check every constraint before comparing cost.
List the required performance and the maximum permitted mass before comparing costs.
