An aid in the mathematical department office gets paid $3 per hour for clerical work and $8 per hour for tutoring. If she wants to work a total of 20 hours and earn at least $145, what is the maximum number of hours X she can spend on clerical work?
\n" ); document.write( "------------------
\n" ); document.write( "Let number of hours of clerical work be \"x\" ; pay for this is 3x dollars
\n" ); document.write( "Number of hours of tutoring is \"20-x\"; pay for this is 8(20-x)= 160-8x dollars
\n" ); document.write( "-----------------------
\n" ); document.write( "EQUATION:
\n" ); document.write( "pay + pay =145 dollars
\n" ); document.write( "3x + 160-8x = 145
\n" ); document.write( "-5x = -15
\n" ); document.write( "x = 3 (number of clerical hours)
\n" ); document.write( "20-x = 17 (number of tutoring hours)
\n" ); document.write( "================
