Question

Darien ordered soda for $2.75, a sandwich for $8.50, and a dessert for $3.85. Sales tax was $1.15. Use mental math to find the total amount of the bill. Explain

Answer 1

What I would do is start with the price of the dessert and the sales tax $3.85+ $1.15= $5. I started with this because when you add the cents they equal a dollar which makes it easier to continue.


Then I would add the 2.75. This would be 7.75.


Then add 7.75 + 8.50. To simplify this, you can add 7 + 8, then .75+ .50

Which would equal 15 + 1.25 + 16.25
