Question

4. Paula and her twin sister Penny go to dinner to celebrate their birthdays. Paula orders a

steak for $22.90 and Penny orders lobster for $27.60. When they get their check, there is
an 8% tax and they tip 18%. Find the total cost of their bill.

Answer 1

$64.36 or 63.63

Explanation:

`22.9+27.6 = 50.5`

To find tax multiply by .08 and then add to the total

`50.5*.08 = 4.04`

`50.5 + 4.04 = 54.54`

I'm not sure of the tip is including the tax or not. However, with tax, multiply the total after tax by .18. Without tax multiply the total beforehand by .18. Then add to the total.

Tip after tax:

`54.54*.18 = 9.82`

`54.54+ 9.82 = 64.36`

Tip without tax:

`50.5*.18 = 9.09`

`54.54+9.09 = 63.63`
