Question

Patrick took his parents to dinner and the bill was $70 plus 6% tax. If he left a tip of 15% of the total (food plus tax), what was the total cost of the dinner?

Answer 1

Answer: $85.33

Explanation:

Bill: $70

Bill + Tax: $70 + $70(0.06)

= $70 + $4.20

= $74.20

Bill + Tax + Tip: $74.20 + $74.20(0.15)

= $74.20 + $11.13

= $85.33
