Its a business question, not a maths question, but here goes. the word and is there so, it means both. yes, it seems the person has got this right it is scarcity (basic supply and demand).
It would be 80 gallons of water that the dishwasher will use to wash 10 loads of dishes. To figure this out you would need to divide 32 by 4 which would equal 8. You would do this to figure out how many gallons of water a dishwasher needs to wash 1 load of dishes. Then you would multiply 8 times 10 which would equal 80. Hope this helps you!
