13-13
If 2500 towels are delivered by hotel, then cost of washing towels = 0.5 x 2500 = $1250
Normal cost of washing 2500 towels = 0.6 x 2500 = $1500
So, The hotel should take the discount as it will help save them $1500-$1250 = $250
13-13 just a home work. Number every examle and pages, make it clear to me, please!
