A contractor is managing three different job sites. It costs her $c to employ a carpenter, $p to employ a plumber, and $e to employ an electrician. The total cost to employ carpenters, plumbers, and electricians at each site is
Cost at site 1 = 12c+2p+4e.
Cost at site 2= 14c+ 5p+3e.
Cost at site 3= 17c+p+5e.
Write expressions in terms of c, p, and e for:
(a) the total employment cost for all three sites
(b) the difference between the employment cost at site 1 and site 3.
(c) the amount remaining in the contractor's budget after accounting for the employment cost at all three sites, given that originally the budget is 50c+10p+20e.
