Jenna offers regular haircuts for $25 and haircuts plus coloring for $42.
\n" ); document.write( " This weekend, had a total of 24 clients and Jenna earned $736.
\n" ); document.write( "how many regular haircuts did she do?
\n" ); document.write( "How many colored haircuts did she do
\n" ); document.write( ":
\n" ); document.write( "let r = no. of regular haircuts
\n" ); document.write( "let c = no. of colored
\n" ); document.write( ":
\n" ); document.write( "Two equation, two unknowns, we can use substitution here
\n" ); document.write( "r + c = 24
\n" ); document.write( "r = 24 - c
\n" ); document.write( "and
\n" ); document.write( "25r + 42c = 736
\n" ); document.write( "replace r with (24-c)
\n" ); document.write( "25(24-c) + 42c = 736
\n" ); document.write( "600 - 25c + 42c = 736
\n" ); document.write( "17c = 736 - 600
\n" ); document.write( "17c = 136
\n" ); document.write( "c = 136/17
\n" ); document.write( "c = 8 colored haircuts
\n" ); document.write( "then
\n" ); document.write( "24 - 8 = 16 regular
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "See if this checks out.
\n" ); document.write( "16 * 25 = 400
\n" ); document.write( " 8 * 42 = 336
\n" ); document.write( "----------------
\n" ); document.write( "total $$: 736
