R=12 because in order to get rid of the 2 in the denominator you have to multiply both sides by 2. Then the equation reads 9r-18<90. Next add the 18 to her 9r<108. And lastly divide by 9 to solve for r. Which in this case is 12

y = yellow marbles
 Sum = b+y
 The <span>chance of a blue marble being drawn first is:

Romashka-Z-Leto [24]
Given:
Mr. Rodriguez :                          6.25
Mrs. R                                        7.50
2 children @ 4.99 each       <u>      9.98</u>
Subtotal:                                 23.73
Sales tax 7.25%                        1.72        *23.73 x 7.25%
Total tip 15%                         <u>    3.56  </u>      *23.73 x 15%
Grand total                            $29.01


Tips should be applied to pre-tax amount not post-tax. However, some companies compute tip based on post-tax amount. This means that the tip you are paying is computed based on the total amount of the meal as well as the sales tax you paid for the meal.
