tom's family is planning a 7-day trip to texas. they want to spend time in both san antonio and dallas.
\n" ); document.write( "they estimate that it will cost $275 per day in san antonio and $400 per day in dallas.
\n" ); document.write( "Their budget for the 7 days is $2300. How many days should they spend in each city?
\n" ); document.write( ":
\n" ); document.write( "you want to write an equation with one unknown here
\n" ); document.write( "Let s = days in S.A.
\n" ); document.write( "then
\n" ); document.write( "(7-s) = days in Dallas
\n" ); document.write( ":
\n" ); document.write( "275s + 400(7-s) = 2300
\n" ); document.write( ":
\n" ); document.write( "275s + 2800 - 400s = 2300
\n" ); document.write( "275s - 400s = 2300 - 2800
\n" ); document.write( "-125s = -500
\n" ); document.write( "s = \"%28-500%29%2F%28-125%29\"
\n" ); document.write( "s = 4 days in S.A. and obviously, Dallas 3 days
\n" ); document.write( ";
\n" ); document.write( ":
\n" ); document.write( "You can check solution by finding the total for each city. \n" ); document.write( "
