Question 616344: I have two problem on a quiz due tonight need simalar exaples to help me work my problems.
. A dehydrated patient needs a 2.6% saline IV. Unfortunately, the hospital only has bags of 8% and 2% saline solutions. How many liters of each of these solutions should be mixed together to yield 2 liters of the desired concentration?
. To buy both a new car and a new house, Tina sought two loans totaling $318,338. The simple interest rate on the first loan was 2.4%, while the simple interest rate on the second loan was 4.7%. At the end of the first year, Tina paid a combined interest payment of $14,761.81. What were the amounts of the two loans?

(8%)(x) + (2%)(2 - x) = (2.6%)(2)



(2.4%)(x) + (4.7%)(318338 - x) = 14761.81
