\n" ); document.write( "Manuel bought 6 candy bars and 3 sodas at the gas station for $8.40. Gary bought 3 candy bars and 4 sodas at the same gas station for $7.45. What is the price of one soda?
\n" ); document.write( "

Let cost of each candy bar, and soda, be C and S, respectively
\n" );
document.write( "Then we get: 6C + 3S = 8.4 ------- eq (i)
\n" );
document.write( "Also, 3C + 4S = 7.45 -------- eq (ii)
\n" );
document.write( "6C + 8S = 14.9 ------- Multiplying eq (ii) by 2 ------ eq (iii)
\n" );
document.write( "5S = 6.5 ------- Subtracting eq (i) from eq (iii)
\n" );
document.write( "Cost of a soda, or  \n" );
