A scientist mixes water (containing no salt) with a solution that contains 35% salt. She wants to obtain 140 ounces of a mixture that is 30% salt. How many ounces of water and how many ounces of the 35% salt solution should she use? Note that the ALEKS graphing calculator can be used to make computations easier.
