Question 96822: Using x for the variable, write an equation that describes the given situation. Then solve the equation.Veronica sold her home for x dollars. The real estate agent's commission was 5% of the selling price and Veronica received $133,000.
I know the selling price is $140,000 through trial and error, but I can't seem to make a complete expression to show how I arrived there.
So if you take $140,000 * 5%, you get $7,000. Subtract $7,000 from $140,000 to get Veronica's profit of $133,000. If I replace the $140k with x, it's still 2 equations, not 1. Please show me HOW to figure out the correct answer.
Thanks!

Question 97123: I am really bad at word problems... If you can give detialed steps it would be great.
The average price of a movie ticke, in dollars, can be estimated by the function P given by: P(x)= 0.115522x-298.592 where x is the year. So, P(2000) is the price of a ticket in the year 2000. Use the function to find the price of a ticket in the years 2007 and 2010. Round to the nearest penny.
I thought it would be solved by 0.15522(2007)-298.592, but this is not the correct answer.
