Answer:

$52.92 has been spent in total for spa treatment and this amount includes a sales tax of $2.52 and a tip of $8.40.

Step-by-step explanation:

Cost of the spa treatment = $42

Percentage of sales tax = 6%

Percentage of tips = 20%

Normally the tips amount is calculated before adding sales tax.

Then

Amount of tips given = (20/100) * 42

                                 = (1/5) * 42

                                 = 8.40 dollars

Amount of sales tax taken = (6/100) * 42

                                          = 252/100

                                          = 2.52 dollars

Then

The total amount spent for spa treatment = (42 + 8.40 + 2.52) dollars

                                                                  = 52.92 dollars

mezya [45]
The have been saving for 10 weeks.

Given:
Duane = $5 every other week. meaning every 2 weeks
Mick = $2 every week
Amount Saved = $45

First, divide Duane's $5 by 2 to get his weekly contribution.
$5/2 = $2.50

let x be the number of weeks.

Duane + Mick = $45
2.50x + 2x = 45
4.50x = 45
4.50x/4.50 = 45/4.50
x = 10 weeks

to check:
2.50x + 2x = 45
2.50(10) + 2(10) = 45
25 + 20 = 45
45 = 45
