Cabrini goes out for dinner and the price of her meal is 18$. the sales tax on the meal is 6% and she also wants to leave a 20% tip. what is the total price of the meal

$22.68

Step-by-step explanation:

First you must find out how much the tax is by setting up a part/whole equation. The equation should look like this . Now that you have set the equation you need to cross multiply. Multiply 18 and 6 and you get 106, then you divide that by 100 and you get 1.06. Now we have to find out the tip by setting up a part/whole equation. The equation should look like this . Now you have to cross multiply. Multiply 18 by 20 and you get 360, then divide that by 100 and you get 3.60. Now you have to add together 18, 3.60, and 1.06. When you do this you will get $22.68. I hope this helped you.

step-by-step explanation:

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
