Sam bought 3 pens for $0.49
each and one notebook for
$1.50. If the sales tax is 6%,
what is the total cost of her
purchase?

The answer should be 3.15

Step-by-step explanation:

Multiply $0.49 by 3 and you get $1.47.

Add $1.59 and $1.47 and you get $2.97

Add $2.97 plus 6% and you get 3.1482

$3.15.

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.
