Question

A scientist has two solution which she labelled, solution A and solution B, each continue salt,she knows that solution A is 65% salt and solution B is 90% salt.she wants to obtained 40 ounce of mixture that is 75% salt,how many ounce of each solution should she use

Answer 1

a = oz of the solution A

b = oz of the solution B



The scientist knows that solution A is 45% salt and solution B is 95% salt. She wants to obtain 80 ounces of a mixture that is 65% salt.



a + b = 80



0.45a + 0.95b = 0.65*80



by solving the above system of equations you'll find····



a = 48 oz



b = 32 oz

~I hope this helped~

If it doesn't make since, I can try to switch up the wording ^^
