The employees from maintenance go for coffee together every day at 9 a.m. On Monday, Hector paid $5.35 for three cartons of milk, six cups of coffee, a seven doughnuts. On Tuesday, Guillermo paid 4.80 for four milks, two coffees, and eight doughnuts. On Wednesday, Anna paid $4.40 for two milks, five coffees, and six doughnuts. On Thursday, Alphonse had to pay for two milks, five coffees, and seven doughnuts. How much change did he get back from his $10bill?
This is kind of confusing, but it would be easiest to use Anna and figure out how much she paid for each individual item, then adding 1 doughnut for Alphonse's order, then subtract that by 10. Hope this helps!!
