SureMath - the math software for 21st century problem solving - was used to solve this problem.



One should avoid starting the problem by setting up a proportional equation. Instead start by responding to what is asked for. If the problem is a proportional problem the correct proportional relation will occur. This avoids errors and produces the solution to problems which are not appropriately solved by proportions.
