The menu price of a sandwich at a restaurant is $6. The meal is subject to a 5% food tax, and Marcy would like to leave a gratuity of 20% on the pre-tax cost. Which plans will work to correctly determine exactly how much money,
including tax and tip, Marcy will need?
Calculate the tax, and then find the tip on the new total.
Calculate the tip, and then find the tax on the new total.
Add the percents to get 25%, and then find 25% of $6 to add to the bill.
Calculate the tip and tax on the $6 total separately, and then add both to the bill.

Calculate the tip and tax on the $6 total separately, and then add both to the bill.

Step-by-step explanation:

Because she wants to the gratuity on the pre-tax amount ($6)

and the the food tax is only on the food ($6), you need to calculate them separately.

Hope this helps.

Add the percents to get 25%, and then find 25% of $6 to add to the bill.

Calculate the tip and tax on the $6 total separately, and then add both to the bill.

Step-by-step explanation:

It's a multiple choice question for me, and I got it right.

answer:

the position of equilibrium will shift to the left.

step-by-step explanation:

the general equation for the dissociation of a weak base is

b + h₂o   ⇌   bh⁺ + oh⁻

according to le châtelier's principle, when a stress is applied to a system at equilibrium, the system will respond in a way that tends to relieve the stress.

if you apply a stress by adding more bh⁺ or oh⁻,   the system will respond by moving in a direction that gets rid of the added ions.

the position of equilibrium will shift to the left, forming more of the undissociated base.
