Hi i have three percentage problems that i am having trouble with. They go as follows:
1. An employee of a consulting firm received a 4% raise in 2004 and a 2.3%
merit increase at the end of 2004. She now earns $2670.82 per month. What
was her monthly wage before the 2003 increase?
2. After selling their house and paying a commission of 5.00%, the owners
received $228,950. What was the actual selling price of the house?
3. 175 ml of pure salt is added to 300 ml of a 23% saline solution. What is the
new percent of salt in the solution?
I have the answer but i wasn't sure about the work i did because i sort deviated from what my teacher taught me which was to use the formula A=RT (where A= amount, R=rate, T=total)
