the forest service must determine how many acres will be needed to make an addition of twenty-two campsites.
\n" ); document.write( " if the existing 24-acre campground accommodates fifty-five campsites, how many additional acres will be needed?
\n" ); document.write( ":
\n" ); document.write( "We can use a ratio equation here. Let a = no. of additional acres required
\n" ); document.write( ":
\n" ); document.write( " $\"%28%28a%2B24%29%29%2F24\"$ = $\"%28%2822%2B55%29%29%2F55\"$
\n" ); document.write( ":
\n" ); document.write( " $\"%28%28a%2B24%29%29%2F24\"$ = $\"77%2F55\"$
\n" ); document.write( "Cross multiply
\n" ); document.write( "55(a+24) = 24 * 77
\n" ); document.write( "55a + 1320 = 1848
\n" ); document.write( "55a = 1848 - 1320
\n" ); document.write( "55a = 528
\n" ); document.write( "a = 528/55
\n" ); document.write( "a = 9.6 additional acres required for 22 more campsites
\n" ); document.write( " \n" ); document.write( "

\n" );
