At a laundromat, it costs $4 for a washer and a quarter for every 10 minutes in the dryer. Samantha does 2 loads of laundry in the wash and then divides all the washed clothes equally into 3 separate dryers. If she lets the dryers run for 40 minutes each, how much does she spend altogether?
Samantha spends $4 x 2 = $<<4*2=8>>8 on washing.
Each dryer costs 25 x 4 = 100 cents = $1
Three dryers cost 1 x 3 = $<<3=3>>3
Altogether, she spends 8 + 3 = $<<8+3=11>>11
