A scientist mixes water (containing no salt) with a solution that contains 35% salt. She wants to obtain 245 ounces of a mixture
sesenic [268]

Answer:

140 ounces of water and 105 ounces of 35% salt solution.

Explanation:

Let x be the ounces of water that need to be added and y be the ounces of 35% solution that need to to be added.

We know that the total of ounces of water and of 35% solution must be 245 ounces:

x+y=245

35% of  x is the salt, and since no salt is added with addition of y  liters of water, this must be equal to the amount of salt in the final 15% solution:

0.35x=0.15*245

we solve for  x and get:

x=105

We put this value into x+y=245 and solve for y to get:

y=140

Thus we have 140 ounces of water and 105 ounces of 35% solution.
