Question 27 • Financial Math - MA2007
The Reed family’s appliances cost 5 + 10 + 90 + 16 = 121 cents per day. The Merrill family’s cost 13 + 10 + 40 + 12 = 75 cents per day, so Reed spends 121 − 75 = 46 cents more each day. Over 30 days, 46 × 30 = 1,380 cents, or $13.80, so the Reed family spends $13.80 more.
