The points (5,-2) and (9,r) lie on a line with slope 3/2
Find the missing coordinate r.

For one night WITH SALES TAX, it would be $154.35, but without sales tax, it would just be $147.. unless you add tip, you would just multipy the original by the percent of the tip then add that answer to the original price.

Solving Steps:

WITH SALES TAX :
$147 x 5% = 7.35 or $147 x .05 = 7.35
147 + 7.35 = $154.35
