Melissa needs to buy some flowers for $5.78, soap for $2.75, and a toothbrush for $1.87. Melissa says that her $10.00 can cover the cost of the items. Is that reasonable?
What is No - Her 10.00 will not cover it because if you round 5.78 to 6.00, 2.75 to 3.00 and 1.87 to 2.00, the total estimated will be $11.00
