Question

1. At the hardware store, you purchased a box of nails originally worth $17.  You had a coupon that took off 20% from the nails.  Sales tax is 6%.  What is the total cost for the nails?  
2. Suppose we are at a restaurant and have ordered $29.31 worth of food and $9.72 worth of beverages.  The sales tax rate is 6% and we wish to leave a 20% tip.  How much is the total we will pay for this meal including tip?  

Answer 1

1. The total cost for the nails is $12.784 rounded to $12.78.

2. The total cost of the meal including tip is $49.65.

Answer 2

1.) You would multiply $17 by 20% to get the discounted price which would be $3.40. Next, you would add $3.40 and 6% to get $3.60 which would be the total cost of the nails.
2.) You would add $29.31 and $9.72 to get $39.03. Next, you would need add the 6% tax so it would become $41.73 and then, add the 20% tip to get the total cost of the food which would be $49.64.
Hope This Helps!
