Hello everyone. I'm new here and need help with some problems. They are the following.
--The selling price of a refrigerator is $843.70 If the markup is 10% of the dealer's cost, what is the dealer's cost of the refrigerator?
--A company wants to increase the 30% peroxide content of its product by adding pure peroxide (100% peroxide). If x liters of pure peroxide are added to 500 liters of its 30% solution, the concentration C of the new mixture is given by the formula below. How many liters of pure peroxide should be added to produce a new product that is 44% peroxide? Formula: C= x+0.3(500)/x+500
I'm struggling with setting up the problems mainly. Thanks in advance!
