Ken purchases a box of cereal for $2.89, cheese for $5.04, lettuce for $1.93, and milk for $1.99. He has $15 with him. About how much change should he expect to receive?
Answer provided by our tutors
The cost of the things Ken bought is: 2.89 + 5.04 + 1.93 + 1.99 = 11.85
Ken has $15. He spends 11.85.
15 - 11.85 = $3.25 or about $3 change.
We can also estimate that he spends about $12 thus he will have change of about 15 - 12 = $3.
