Question

Tessa grabbed a quick bite to eat during her lunch break. She purchased an $8.50 sandwich and a lemonade for $1.99. She tipped the barista 15% and paid a 6% sales tax. Note: The sales tax and tip are each based on the cost of the food and drink, only.

Answer 1

$12.78 is the final price

Explanation:

8.50 + 1.99 = 10.49$

15% ÷ 100 = 0.15

0.15 x 10.49 = 1.5735

round to the nearest hundredth

= 1.57 + 10.49

= $12.06

6% ÷ 100 = 0.06

0.06 x 12.06 = 0.7236

round to the nearest hundreth

= 0.72 + 12.06

= 12.78$
