To paint the gym for homecoming, Senate needs 25 gallons of lead paint and has $141 dollars budgeted for the project. If the blue lead paint costs $5 a gallon and the gold lead pain costs $7, how many gallons of each color of lead paint should they buy. Solve by using a system of equations, show all your work.
\n" ); document.write( "Quantity:: b + g = 25 gallons
\n" ); document.write( "Value::: 5b +7g = 141 dollars
\n" ); document.write( "----------
\n" ); document.write( "Modify for elimination:
\n" ); document.write( "5b + 5g = 5*25
\n" ); document.write( "5b + 7g = 141
\n" ); document.write( "----------------
\n" ); document.write( "Subtract and solve for \"g\"::
\n" ); document.write( "2g = 16
\n" ); document.write( "g = 8 (# of gallons of gold lead paint)
\n" ); document.write( "-----
\n" ); document.write( "Solve for \"b\"::
\n" ); document.write( "b = 25-g
\n" ); document.write( "b = 25-16 = 9 gallons (# of gallons of blue lead paint)
