Algebra Homework Problem. I'm supposed to put the information into an equation, then solve.?

Question

The hit movie Titanic earned more in Europe than in the United States. As of September 1998, the average cost for a movie ticket in the United States was $4.59. In Great Britain, it cost $10.59 and in Germany, $8.42. If 74 million tickets were sold in Great Britain and Germany, how many would have to be sold in each country to earn $686 million? Round answer to the nearest million.

I'm only on the chapter that uses one type of variables per equation; in otherwords, i'm supposed to set this equation up using on Xs but not Xs and Ys. In that case, the first answer given by David may be very well be correct, but it's not an acceptable answer for me to turn in at my level. Since I am only working with 1 variable per equation, can u show me how to set this up if i were to only use, say, X variables without the Y variables.

Answer 1

Extra information: Movie ticket in U.S. So ignore that.

The number of tickets sold were 74 millions. Let x equal tickets sold in Great Britain and y equal tickets sold in Germany. From the above, we know between the two, they sold 74 million tickets.

x + y = 74 (you don't have to worry about the million since we are rounding to the nearest million)

for the price, we go price of ticket in Great Britain * x + price of ticket in Germany * y , which has to equal 686 million. This equation is the following:

10.59x + 8.42y = 686 (again ignore the million)

From these two equations, solve for x and y.
