Question

Damon treated his sister to lunch while visiting her in Weston. Thier lunch cost $40, and the sales tax in Weston is 15%. If Damon left a 20% tip on the $40, how much in total did he pay?

Answer 1

Given:

Cost of lunch = $40

Rate of sales tax = 15%

Rate of tip = 20% on $40.

To find:

The amount Damon pay.

Solution:

We have,

Cost of lunch = $40

Rate of sales tax = 15%

`\text{Sales tax}=(15)/(100)* 40`

`\text{Sales tax}=6`

Rate of tip = 20% on $40

`\text{Tip}=(20)/(100)* 40`

`\text{Tip}=8`

Now,

Total amount = Amount + Sales tax + Tip

=
`40+6+8`

=
`54`

Therefore, Damon pays total $54.
